Product introduction

air cooled system

EXP systems – Multi-purpose ecological air-cooled system with axial fans. Range with hermetic Scroll compressors and R410A refrigerant gas.

Construction features

• Compressor: scroll type, rotary, hermetic complete with thermal protection and casing heater.
• Up to 6 capacity steps with high efficiency at partial loads.
• Main and secondary heat exchangers: crossed flow stainless steel plate exchangers, complete with antifreeze heater, closed cell polyurethane foam rubber insulation and water flow differential pressure switch.
• Air side heat exchanger: finned coil with copper pipes and aluminium fins.
• Fan: external rotor axial type electric fans, equipped with internal thermal protection, accident protection grilles and a proportional electronic device for continuous fan rotation regulation (T version; fans with an EC motor are standard in the Q version)
• Control: microprocessor electronic control with Adaptive Function Plus logic.
• Structure: load bearing structure made of galvanised sheet steel and painted with polyester powders.
• The unit is also complete with:
– fan and compressor circuit breaker switches, heat exchanger antifreeze heater;
– display of cooling circuit high and low pressure;
– electronic expansion valve;
– clock board.


• T – High efficiency version.
• Q – Supersilenced version complete with soundproofed compressor technical compartment, super-low fan fans with EC motor.


• TXAETY: EXPsystems unit.
• TXAEQY: supersilenced EXPsystems unit.
