X-Series Cooling Units

The X-Series cooling units represent a significant advancement in thermal management technology. Designed for energy-efficiency with precise temperature control through inverter technology.  Notably, the X-series units are interchangeable with the Green Series and older Pfannenberg cooling units, thanks to their consistent installation cut-out dimensions. This interchangeability, coupled with quick assembly properties, facilitates the easy implementation of energy-saving cooling solutions even during ongoing production. With cooling capacities ranging from 1,000 to 4,500 W and the inclusion of a premium controller, these units are engineered to deliver powerful, accurate, and energy-efficient cooling.

Why Choose Pfannenberg X-Series Cooling Units?

Flexible

Utilizing inverter technology, each unit covers a wide range of cooling capacity making each unit highly versatile.

Connectivity Ready

Comes standard with RS485 interface to enable communication via Modbus RTU protocol.

Quick Installation

Cutout is compatible with other Pfannenberg units for easy upgrade. Available in both recessed mount and side mount to save floor space.

Energy Efficient

The variable speed compressor will adjust according to the application requirement using less energy compared to fix speed compressor. The variable speed components combined with Pfannenberg years of experience optimizing the control algorithm leads to significant energy savings for customers.

Precise Cooling

Designed for precision cooling with accuracy of +/-0.1 K (0.2degF).

Multiple Mounting Styles

Available in both recessed mount and side mount to save floor space.

Precision Cooling for Efficiency

Inverter technology combined with years of experience in control algorithms eliminates the temperature spike within the cabinet seen in single speed compressor cooling units. This system provides more consistent cabinet temperature protecting the sensitive components inside (refer to the solid red line). The inverter technology allows the cooling unit to operate at partial load by only cooling to the heat load (red dotted line) inside the cabinet to reduce energy consumption (refer to green line).

Multiple Mounting Styles

Available in both recessed mount and side mount to save floor space. One cut out size for models of different capacities.

Easy Installation and Maintenance

Tool-free spring plate design keeps the unit safely in place and allows mounting by 1 person in less than 3 minutes with 55% lower mounting costs. Direct access to the PCB and the fans means 80% shorter repair times.

Thermal Overload Protection

Compressor and fan motors are outfitted with integral temperature switches to shut down the unit in the event of excessive temperature.

Protection Overload Protection

High pressure cutout switch ensures safety by shutting off the compressor in the event of excessive pressure appearing in the refrigeration circuit.

Closed Loop Design

Designed to isolate the external ambient air from the internally conditioned air eliminating the risk of contaminants entering the cabinet.

Thermal Expansion Valve

Regulates the flow of refrigerant based on thermal demand for efficient performance over the entire operating temperature range.

Efficient Circulation

Large distance between intake and exhaust vents for efficient air circulation and elimination of hot spots.

External Display

For visual temperature monitoring.

Optional Filter Design

In high particulate environments, optional filters could be ordered for easy retrofitting without needing tools.

High Airflow Backward Curve Impeller Fan

Provides high airflow in a long lasting, single bearing design. Outperforms typical two-bearing blowers with nearly twice the lifespan.

Hermetically Sealed Compressor

The absence of any refrigerant fill valves eliminates leak paths. Recharging is never needed. 100% cooling capacity efficiency is ensured.

Active Condensate Management

Condensation is a natural byproduct of refrigeration. The heated condensate collection pan boils this off thereby eliminating the need for drain tubes and buckets. To conserve power, this heater only activates when necessary.
