Spring Cleaning – 3 Steps you Can Take to Prepare your Cooling Units for the Stress of the Summer Heat

/in , , , , /by

With hotter temperatures just around the corner we’ve put together this Preventative Maintenance Video to help you prepare your enclosure cooling units for the stress of summer heat.

To avoid any critical component failure, follow the 3 simple steps below to help ensure your enclosure cooling units stay up running all summer. Don’t Wait Until it’s Too Late!

STEP 1: Make Sure your Condenser Coils are Clean

The condenser coils are one of the most important components of your Cooling Unit, they ensure the reliable, cost efficient and long-term operation of your unit. When dirt, dust or debris builds up on your condenser coils, it can have a major effect on the performance of your cooling unit.

STEP 2: Check your Fan Motors and Inside/Outside Electrical Components

In order to prevent failure, the cooling unit’s fan motor and fan blades need to be inspected to determine wear and damage.  All the electrical components in the control box also need to be checked to make sure all connections aren’t damaged or loose.

STEP 3: Set your Unit to the Recommended Proper Temperature

Pfannenberg sets the dip-switches on the control board to 95°F/35°C in the factory, and recommends that the dip switch settings are not altered.

*Having the dip-switch temperature set to a lower point can cause damage not only to the cooling unit, but to the composure as well.  Changing the set point can cause the cooling unit to run excessively, possibly causing damage to the compressor and other components.  It can also cause the enclosure to produce condensate, possibly damaging electrical components inside the cabinet.

/in , , , , /by

Visit booth #561 to see more efficient, high-performing air to air heat exchanger

Pfannenberg will highlight their advanced Pfannenberg Kinetic System™ Series Air to Air Heat Exchangers for removing heat from VFD control panels at booth 561 at the 2019 EASA Convention in Las Vegas, NV, held from June 30th to July 2nd.

Additionally, Pfannenberg will be presenting their new PKS system and how this solution could improve the reliability of VFDs while reducing energy consumption and maintenance compared to other thermal management products on Monday July 1st at 2:30 PM at the New Product Theater.

Perfect Solution for VFD control panels Cooling

Pfannenberg’s PKS Series Air to Air Heat Exchangers use a revolutionary next generation cooling technology (Pfannenberg Kinetic System™) to remove heat from VFD control panels while preventing ingress of contaminants into the enclosures. These environmental parameters within the VFD cabinet, temperature and dust, could determine the service life of the VFD.

A VFD running at 18°F above its recommended ambient temperature could lose up to 50% of its expected service life. Industrial air conditioners are typically the go-to solution for cooling VFDs and other critical electronics housed in sealed enclosures. However, a cooler ambient environment could also be used to help control the temperature within the cabinet. Lightweight and easy to install, the PKS technology takes advantage of a cooler ambient environment to remove heat from within the enclosures while sealing against gas, humidity, and dust. The patented technology, unlike industrial air conditioners, does not utilize a refrigerant cycle that has a high energy consuming compressor, making it more efficient to operate from a uptime reliability and energy savings standpoint.

PKS Series Air to Air Heat Exchangers

PKS Series Air to Air Heat Exchangers are designed for indoor (NEMA Type12), outdoor (NEMA Type 3R), and washdown (NEMA Type 4X) applications that require protection from harsh ambient conditions.

They are also ideal for keeping water and dust from sensors and drives on outdoor systems, and protecting against corrosion and contamination in the food and beverage industry.

This is a perfect solution for those looking to reduce the energy, maintenance and footprint associated with traditional enclosure cooling units. This new technology offers considerable saving compared to a traditional AC unit.

In addition, with only two mechanical elements, PKS Series Air to Air Heat Exchangers require less maintenance and ensure greater uptime!

Why Pfannenberg’s Cooling Units Do Not Need A Filter

/in , , /by

Pfannenberg’s ‘service-friendly’ DTS cooling units provide effective cooling for tough industrial or outdoor applications. Their closed-loop designs ensure that ambient air, dust, and humidity are not passed to the interior of the enclosure, thereby keeping sensitive and critical electronics safe from contamination and in prime operating condition.

Pfannenberg’s DTS Cooling Units filter-less design reduces the amount of required maintenance needed for operation in dirty environments. Indeed, if a dirty filter is not cleaned or replaced, it can become clogged which severely limits its efficiency and result in poor performance.

Filter-Less Design

  • High Airflow Backward Curve Impeller Fan
    Provides high airflow in a long lasting, single bearing design. Higher airflow pushes dirt through wider fin spacing allowing for less clogging which avoids system failure.
  • Large Fin Spacing
    Large condenser fin spacing allow for longer maintenance periods, even without an additional Nano coating. They are less susceptible to clogging from dirt buildup which can cause the unit to work harder and hamper efficiency.
  • Corrosion Protection
    The DTS Outdoor and wash-down units have a special coating on pipes and coils on the ambient side of the unit to provide maximum protection from saltwater, sour gas, and other corrosive substances.
  • Self-Protected Electronics
    Our unit is uniquely designed to protect itself in NEMA 3R, 4, and 4X environments. An example of this is the location of our control electronics within our dry, cool interior circuit.

 

How to Avoid System Failure

As with any unit located in a dirty environment, the components around the external air circuit require periodic cleaning. To avoid any critical component failure, follow the 3 simple steps below to help ensure your enclosure cooling units stay up running:

  • STEP 1: Make Sure your Condenser Coils are Clean
    When dirt, dust or debris builds up on your condenser coils, it can have a major effect on the performance of your cooling unit.
  • STEP 2: Check your Fan Motors and Inside/Outside Electrical Components
    The fan motor and fan blades need to be inspected to determine wear and damage.  Also make sure electrical components aren’t damaged or loose.
  • STEP 3: Set your Unit to the Recommended Proper Temperature
    Pfannenberg recommends the dip-switches on the control board to 95°F/35°C in the factory.

All maintenance should be performed by qualified personnel, following all safety procedures. To help you perform your preventative maintenance, Pfannenberg realized a simple video following the 3 above steps: Watch the Full Video Now!

Stronger than the elements – Pfannenberg’s DTS 3000 series Outdoor Thermal Management Devices

/in , , /by

When conditions are harsh you can count on Pfannenberg’s DTS 3000 series cooling units to protect your electronics in extreme heat, cold, wet or dusty environments.

System integrators and planners often struggle with the thermal management of electrical enclosures in outdoor applications: extreme temperatures, moisture and dust are particularly challenging with some applications exposed to the elements 24/7. Pfannenberg, the world leader in the Thermal Management of electrical enclosures, has designed a range of cooling units which represent a solution to providing protection in these harsh environments.

DTS cooling Units

Pfannenberg’s DTS 3000 series Cooling Units, cooling capacity from 300W to 6.3kW, are suitable for use in demanding outdoor locations. These products are categorized in protection classes NEMA Type 4/4X and IP 66. Pfannenberg also offers heaters, thermostats and hygrostats to prevent the formation of damaging condensation.

Typically, these cooling units are used for applications in demanding environments such as deserts or extreme cold, in buildings, traffic and energy technology, in sewage and water treatment plants and in metal production/processing. They are also found in other harsh manufacturing systems for cement and building materials, the timber industry, wind,  water power generation and photo voltaic applications. Users even rely on these versatile devices in mobile equipment. Pfannenberg’s DTS 3000 series cooling units are therefore making a contribution to the energy transition.

“Pfannenberg is focusing on the growing global market for demanding outdoor cooling systems. We have have a name in the thermal management of electrical enclosures for indoor applications and with an extremely broad portfolio of devices which also meet the NEMA standard, we can cover almost every application scenario,” says Jörg Achenbach, Regional Product Manager, Thermal Management for Pfannenberg EMEA.

“Outdoor conditions are often extreme: wildly fluctuating weather situations like rain, frost and heat all present problems as do a high concentration of particles in the air, hail, snowstorms, aggressive vapors and cleaning with powerful water jets and cleaning materials. Pfannenberg offers solutions in the DTS 3000 series for all these environmental conditions, with models that can operate in temperatures ranging from -40 °F to maximum 140 °F”, explains Achenbach.

 

Robust and reliable

Pfannenberg’s DTS 3000 series offer powder-coated NEMA 3R/4 but also Type 4/4X 304 Stainless Steel units for use under the toughest conditions. A hermetically sealed cooling circuit not only ensures prevention of leaks, but also makes topping up with coolant unnecessary. Systems to protect against thermal overload, corrosion and excess pressure ensure that these outdoor cooling units have a longer operational life.

 

Dust and moisture remain outside

To prevent ingress of foreign bodies, dust or water, Pfannenberg’s outdoor cooling units meet the requirements of IP 56 and N3R protection classes as standard. Also, the DTS 3000 outdoor units condensers fins are 3 mm apart which makes them less likely to trap dust. One of the advantages of this design is that the units are almost completely maintenance free – even with very high concentration of particulate in the air.

 

Low Ambient (LA) equipment package for low temperatures

The Low Ambient (LA) anti-frost package has an integrated enclosure heater and an intelligent fan control system to ensure that the machinery operates without interruption and provides excellent protection from condensation at temperatures as low as -40 °F. The extracted moisture evaporates in the device before it can cause damaging short circuits in the enclosure. The package also includes a safety overflow and a thermostat which can be installed in the enclosure. The LA package is available with cooling capacities from 700W to more than 5kW for the DTS 3000 cooling units. The integrated electrical enclosure heater, which is very easy to install, is offered in versions up to 3kW.

 

High Temperature (HT) package for extreme heat

The High Temperature (HT) package has a temperature-stable compressor and a large condenser for reliable protection of enclosure components at exceptionally high temperatures up to 140 °F. The HT package is available for compact 700W cooling devices and also for large, powerful solutions up to 3200W.

 

Even better equipped

Compact fan heater with thermostat

As a useful addition to the outdoor cooling devices, Pfannenberg offers 10W – 1200W supplementary heaters, thermostats and hygrostats for monitoring relative humidity levels. Depending on the application, this additional equipment offers further protection from condensation and corrosion and helps to optimize the energy/cost ratio. 

As a system: cooling units, heaters, thermostats and hygrostats will ensure that the environment within the enclosure is ideal for performance and service life of the critical electronics.

KUADROTEK – Cooling the cabinets of the inverter stations for the 35 MW Ashalim photovoltaic plant, in Israel.

/in , , , /by

The plant includes the world’s tallest solar tower

The Ashalim power station is located in the Negev desert near the kibbutz of Ashalim, in Israel. The station will provide 250 Megawatt of hybrid PV-solarthermal electricity (2.5% of the Israeli consumption), which makes it the largest of its kind in Israel and one of the largest in the world. The station will combine 3 kinds of energy: solar thermal energy, photovoltaic energy, and natural gas. The PV plant has been connected to the grid in January 2018. Pfannenberg’s cooling units have been mounted in Kuadrotek’s cabinets for inverter stations.

The Customer

Kuadrotek SA, from Tarragona, is part of the Spanish Elektra Group. It specialises in the design, development and implementation of electric switchboards and control panels for the automation of installations and industrial processes in the automotive and energy industries.

Kuadrotek has delivered the electrical cabinets for the inverter stations of the 35 MW photovoltaic plant. Pfannenberg’s cooling units will ensure the perfect thermal management and operational safety for their components.

The Application

PV power plants are built across the globe, including areas of high altitude, extreme temperature, proximity to the sea, and desert areas impacted by sand and dust.

The inverter is the heart of every PV plant; it converts direct current of the PV modules into grid-compliant alternating current and feeds this into the public grid. At the same time, it controls and monitors the entire plant.

Controlling the temperature inside the electrical cabinets – and therefore guarantee the health of its components – it’s a crucial task.

The Solution

After taking into consideration different options of the competition, Kuadrotek chose Pfannenberg’s Outdoor Type 3R/4 side mount cooling units – model DTS 3161 230 V – because of the high protection level (comparable to IP 56) together with the reliability of working in extreme conditions. It offers a cooling capacity of 1235 W in a very compact design – 395 x 748 x 237 mm only.

It is available in 3 models; DTS 3141 (NEMA Type 12) for indoor use, DTS 3161 (NEMA Type 3R/4) designed for outdoor use, and the stainless steel DTS 3181 (NEMA Type 4/4x) designed for washdown applications.

The full DTS 3000 series was designed utilizing high temperature compressors and larger condensers to best perform in outdoor applications which require a maximum ambient temperature of 55 °C – such as roadside, rooftop or desert locations.

NEMA rating can be compared with IP rating – although there is no direct correspondence – but the first one is more complete and also includes other factors such as the protection from corrosion. NEMA Type 3R/4 is equivalent to IP 56. Moreover, Pfannenberg cooling units from NEMA series are UL listed.

 

“Our relationship with Kuadrotek is strengthened thanks to the reliability of the products already used in other large photovoltaic plants in the world. This is also why Kuadrotek continues to choose our products over our competitors.” Xavier Pedescoll – Sales Area Manager. Pfannenberg Iberia
