Cooling AND heat pump technology

High quality and flexibility for all individual application requirements are continuously ensured at the factory by the WOLF Refrigeration Engineering department. Furthermore, you can rely on a competent and strong partner in the planning, implementation and support of your cooling applications.

• Refrigeration units for cooling or dehumidification.
• Fully integrated chiller with condenser coil in the exhaust air or with external condenser.
• Internal or external refrigeration pipework depending on customer-specific unit layout.
• Units with heat pump circuit for cooling/heating.
• Utilisation of waste heat in the supply air in dehumidification units (reheating coil).
• Extract air heat pumps for transferring waste heat to water.
• Special unit for rooms with thermal loads all year round.
• Swimming pool units with and without pool water condenser.

The refrigeration unit is fully installed in an empty, sound-insulated section of the KG Top, in the extract air flow of the central ventilation unit. Retrofitting is easy, even with appliances from other manufacturers. The integral refrigeration units from WOLF offer several important benefits that you should consider during the design stage.

• Matched refrigeration and control components.
• Clearly defined warranty limits, particularly in conjunction with an overall system control panel from WOLF.
• Systems with variable output control (digital scroll technology and inverters).
• High performance ratings (EER/COP) and efficiency levels.
• No energy losses through water as an intermediary heat carrier.
• Combination with adiabatic extract air cooling.
• Space saving – no additional outdoor unit required for cooling.
• Indoor units – no equipment required on the roof (listed buildings).
• Treatment of the extract air flow required for hygiene reasons.
• Compressor in air flow – optimum compressor cooling.
• Compressor set in separate component for easier servicing during operation (optional).
• Refrigeration pipework fitted at the factory or on site.
• Serviced by the manufacturer.

The compressor/compressor set is installed on anti-vibration mounts. Assembled as one compact unit, it incorporates intake and pressure shut-off valves and a crankcase heater with a refrigerant collector, refrigerant dryer, sight glass, high/low pressure switches and an electronic or thermostatic expansion valve.

If there are several compressors in the refrigeration circuit, the units are also equipped with an oil regulation system, and are pressure-tested, evacuated and filled with shielding gas in their delivered condition. WOLF refrigeration units feature the necessary safety equipment in accordance with UVV/VGB 20 and are assembled and tested in line with the relevant standards and regulations.

A control panel for operating the refrigeration unit, sheet steel casing, a mounted door with rubber seal and the cam lock, RAL 7035 paint finish, contactors, fuses, etc. on the mounting plate with wiring ducts, main switches and indicator lights in the door with flexible wiring, fully assembled and partially wired, tested to VDE 0660 Part 500 and EN 60439-1.

Final installation of the refrigeration pipework, wiring of the refrigeration components to the refrigeration control panel and commissioning of the compressor set on site with pressure testing, commissioning report and user instruction.

• A fully functional unit is assembled from all compressor set components at the factory.
• Precise temperature control and efficient operation.
• Output controlled compressor set with controllability down to very low ranges in partial load operation (down to 10 %).
• Complete safety chain with high and low pressure monitoring.
• Load shedding circuit possible using the WOLF overall system control panel.
• Straightforward mechanism for robust, uninterrupted operation.

• A fully functional unit is assembled from all compressor set components at the factory.
• Variable temperature control and efficient operation.
• 4, 6 or 8 stage compressor set.
• Load shedding circuit already integrated in the refrigeration control panel.
• Communication with the WOLF overall system control unit via bus.
• Self-supporting base frame – if the compressor section has to be taken apart for handling, the compressor set itself can be handled separately as a single component.
