The new range of UNIFLAIR ARA water chillers and heat pumps features state-of-the-art technology to give
maximum reliability, safety, quietness of operation and respect for the environment.
1) RELIABILITY: Trouble-free operation of Uniflair precision chillers is ensured by rigorous production
process controls under ISO 9001-certified quality procedures:
• quality control of components;
• pressure testing of refrigerant and water circuits;
• testing of current absorption and IEC safety testing;
• calibration and testing of instruments and safety devices;
• final testing of unit under operating conditions
2) ACTIVE SAFETY: UNIFLAIR safety and control systems have a supervision and prevention function
with:
• automatic blocking of components in dangerous conditions;
• indication of function status; reading and continuous display of circulating fluid temperature;
• management of compressor start-ups to reduce excessive switching on and off
• compressor start timing to reduce total unit start-up current
• indication of anomalous function conditions and/or alarms.
3) PASSIVE SAFETY: The essential functions of UNIFLAIR chillers are protected against anomalous
function conditions and potential damage with:
• high and low pressostats on the refrigerant circuit (HP with manual re-set)
• safety valve on the high pressure refrigerant line
• anti-freeze protection to prevent freezing of the evaporator, pump and tank
• compressor motor electrical protection
• standard differential flow gauge
• water circuit safety (with optional pump group)
• compressor crankcase heater (standard on free-cooling and heat pump versions).
4) PERSONAL SAFETY. The design and cabling of all UNIFLAIR chillers conforms to IEC electro-
technical norms. Electrical panels have auxiliary 24V circuits and are equipped with:
• general switch and door lock switch;
• automatic circuit-breaker switches;
• double protection panel on fan compartment.
The fans are protected by an external metal grille which conforms to applicable safety norms.
