The HYDROCIAT LW liquid chillers are the premium solution for industrial and commercial applications where installers, consultants and building owners require optimal perfor-mances and maximum quality. The HYDROCIAT LW liquid chillers are designed to meet current and future requirements in terms of energy efficiency, flexibility of use and compactness. They use the most reliable technologies available today: Twin-rotor screw compressors with a variable capacity valve Refrigerant R134a Connect Touch control system Flooded heat exchangers that are mechanically cleanable To meet to all environmental and economic requirements, the HYDROCIAT unit is available in two efficiency classes: Entry-level efficiency LW ST units that offer an optimised balance of technical and economical aspects, Premium-efficiency LW HE units that offer unequalled energy efficiency to satisfy the most stringent demands of building owners wanting to reduce operating costs to the minimum. The HYDROCIAT range is also split into two applications: - LW for air conditioning and refrigeration applications - Option for heating applications As standard, the HYDROCIAT can provide an evaporator leaving temperature down to 3,3°C (-12°C optional), and when operating as a heat pump, it can deliver up to 50°C (63°C optional) on the condenser side.
Low energy consumption
- EER of up to 5,9 and ESEER up to 6,8 - Eurovent energy efficiency class “A” - The high energy efficiency is reached through: • Twin-rotor screw compressor equipped with a highefficiency motor and a variable capacity valve that permits exact matching of the cooling capacity to the load. • Flooded multi-pipe heat exchangers for increased heat exchange efficiency. • Electronic expansion device permitting operation at a lower condensing pressure and improved utilisation of the evaporator heat exchange surface. • Economizer system with electronic expansion device for increased cooling capacity (LW HE).
Easy and fast installation
Compact design - The LW units are designed to offer the most compact dimensions on the market. - With a width of approximately 1 m up to 1600 kW the units can pass through standard door openings and only require minimum floor space in the plant room. Compact, accessible unit side view - sizes up to 1600 KW
Low operating sound levels
Standard unit features include: - Silencers on the compressors discharge line. - Silencers on the economiser return line. - Acoustic insulation on the components that are most subjected to radiated noise. - Low noise level option further reduces the global unit sound level.
Simplified electrical connections - Main disconnect switch with high trip capacity - Transformer to supply the integrated control circuit (400/24 V) Simplified hydronic connections - Victaulic connections on the evaporator and condenser - Practical reference marks for entering and leaving water connections - Possibility to reverse the heat exchanger water inlet and outlet at the factory - Possibilty to modify the number of heat exchanger passes Fast commissioning - Systematic factory operation test before shipment - Quick-test function for step-by-step verification of the instruments, expansion devices and compressors.
