Life Support Equipment Environmental Control Unit
Underwater Technology Services (UTS) manufactures in house the Life Support Equipment that it features in all UTS manufactured Saturation Dive Systems. Assembled using the highest quality of standardized mechanical and electrical parts, our entire package is manufactured here in Singapore.

Standardization is an important concept here at UTS; We utilize the exact components across our fleet of equipment as far as possible so as to keep costs and problems with inventory down in the operational endeavours of our Clients. The effectiveness and durability of our equipment has been attested to in regions with a wide variety of climate conditions such as Australia, New Zealand, Brunei, Malaysia, the Arabian Gulf, the Gulf of Mexico, China, Korea, India, Sakhalin, Vietnam & Indonesia.

UTS Manufactured Environmental Control Units (ECUs) have a semi hermetically sealed refrigeration compressor and associated control equipment. The condenser is salt water cooled, and the compressor delivers compressed refrigerant to two solenoid valves which are controlled by temperature controllers on the electrical panel. The two solenoids control the flow of refrigerant to two heat exchangers through which chilled water is delivered by circulating pumps to the DDC dehumidification heat exchanger and the temperature control heat exchanger.

UTS has two distinct models of ECUs, but can manufacture these units in a either single or double configuration to cater to your needs for a system with complete redundancy.
