- HIGH EFFICIENCY FINNED CONDENSERS
High efficiency finned coils condensers allow the cooler to operate even with high environmental or water temperatures. Copper pipes and aluminum fi ns ensure high performance heat exchange and durability. - HIGH EFFICIENCY RECIPROCATING COMPRESSOR
The use of reciprocating compressors technology ensures total reliability together with high effi ciency levels. - GALVANIZED STEEL FRAME
The unit is supplied in a galvanized steel frame, chosen for its rust resistance, durability, strength, corrosion protection, and long-term reliability. - INTERNAL HYDRONIK KIT
Each RPP chiller has an internal Hydronik kit, sized and powered based on its dimensions.
- PLATE EVAPORATORS
Brazed stainless steel plate evaporators,characterized by maximum reliability and heat exchange effi ciency. These heat exchangers ensure great compactness and versatility. - AXIAL FANS
Axial fans for maximum-effi ciency and minimumconsumption cooling of the refrigerant gas passing through the fi nned coils. - HIGH EFFICIENCY PUMP
Centrifugal pump with wide operating range, ensures maximum-effi ciency of the cold water fl ow rates for utilities. - USER FRIENDLY PLC CONTROLLER
Touch Screen PLC for temperature control, zone management, and serial connections, with a clear, intuitive interface.
Typical Setup
In the best setup, the propane chiller is placed inside the building, seamlessly integrating with the arena’s existing refrigeration system. As illustrated in the image, this arrangement helps reduce heat loss, boosts energy efficiency, and enhances overall cooling performance.

Main optional & accessories
/ 01
Double pump
Double utility pump, operating with a working pump and a spare pump. The automatic rotation of the pump operation is managed by software to control the wear of the pumps.
/ 02
User pump inverter
Ideal solution to guarantee maximum system effi ciency even with a variable load.
/ 03
Special voltage options
It is possible to choose the most suitable type of unit power supply (voltage and frequency) from a wide range of possibilities.
/ 04
Low noise
Axial fans available with a special diff user allowing for a considerable reduction in sound pressure compared to the standard version.
/ 05
Remote panel
One or more refrigeration units can be controlled by using remote panels. These can be interfaced via serial link (CANBUS), with touchscreen panels, or via ethernet connection (via IP addressing) using PCs and mobile devices. For maximum system fl exibility, other types of protocols can be used, such as PROFIBUS, PROFINET and MODBUS TCP.
