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

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.

Pfannenberg Installs Sounders at the Distribution Hub of One of the World’s Largest Online Retailers

Standard-compliant alarm system: 96 PATROL Sounders in a  100,000 sq ft. warehouse

Pfannenberg has equipped a distribution hub of one of the world’s leading online retailers with Audible Signaling Devices for emergency evacuation. Pfannenberg used its practice-based planning system “Pfannenberg 3D Coverage” to design an ideal signaling solution for a space covering more than 100,000 sq ft. with high bay racks and high ceilings.

 

3D Coverage for Audible Signaling Devices 

It is important to plan the emergency evacuation alarm system for a noisy and hectic environment such as that of a logistics center. Early and professional planning of the signaling devices is particularly important in order to ensure emergency evacuation alarms comply with standards in a cost-efficient manner. Despite high shelves and significant noise levels, the online retailer was able to implement a signaling solution with the help of a system integrator and the use of Pfannenberg’s 3D Coverage method to meet all relevant standards and ensure that every worker in this large logistics center is effectively alerted in case of an emergency. In addition, data-based planning ensured proper sizing of the emergency evacuation alarm system: An undersized system involves a high-risk potential while over sizing represents unnecessary costs.

“Current norms state that the sound generated by acoustic signaling devices must exceed the ambient noise level by 10 dB(A) at all times. This often makes it difficult for planners and alarm specialists to determine the number of devices required to provide an alert through large spaces that will comply with standards but at the same time are cost-effective. The information traditionally supplied on technical data sheets by many manufacturers however, don’t allow conclusions to be drawn about the actual product performance in a given space. 3D Coverage shows the actual product performance and helps to achieve a safe solution, select the right products and save costs through correct sizing.”

Safety through visible signaling area

The 3D Coverage planning method makes it possible to determine and design the signaling range actually covered by acoustic signaling devices in relation to the height, width and length of the space throughout which the signal is to be heard. With 3D Coverage integrated in Pfannenberg’s free “Pfannenberg Sizing Software” (PSS), the electrical engineering specialists succeeded in designing the optimal signaling solution. The software not only calculates individual values, but also provides a qualified recommendation for suitable signaling devices and their positioning.

Planning reliability and cost savings

The calculations showed that 96 sounders of the PATROL series were required to alarm the logistics center with an area of more than 100,000 sq ft. at a calculated noise level of 85 dB(A). Furthermore, the calculations showed that PATROL sounders with 120 dB(A), were the perfect solution for this application, being powerful enough for covering the necessary signaling range and allowing for a simple and time-saving installation. This significantly reduced the number of sounders required compared to similar models available on the market.

The 3D Coverage display method used provided reliable protection against incorrect sizing and allows for reliable compliance with industrial norms and regulations, and optimum cost efficiency. Thanks to intelligent planning, the online retailer was able to save material and servicing costs.
