Aqu@Logic Centrifugal Fan Air Cooled Water Chillers
The new range of AQCL air cooled
water chillers with centrifugal fans is composed of 11 models covering a nominal cooling capacity range from 25 to 125 kW. (2.5 l/kW) and thus eliminating, for the majority of comfort air conditioning applications, the need for a buffer water tank. AQCL represents a new generation of innovative air cooled
water chillers, integrating components using the very latest technological advances.These components provide AQCL
water chillers with considerable advantages in terms of compact design and improved efficiency and reliability.All AQCL
water chillers are equipped with ILTC (Intelligent Liquid Technology Chiller) control providing optimised control across the unit’s entire operating range.
As standard equipment, each unit has two compressors, fitted in tandem, for adapting to partial system loads.Pressure and temperature sensors provide data to the electronic control system for taking account of the prevailing operating parameters in order to optimise system performance.This intelligent control system enables water temperature to be maintained within the required range, whilst only using a small volume of water
Features and Benefits
A maximum of technology
a high Coefficient Of Performance (COP), fitted in tandem on all models in the range. The new generation of AQCL ILTC control. air cooled
water chillers integrates high technology components :- Scroll compressors.
- Brazed stainless steel plate heat exchangers.
- Microprocessor based - HFC 407C refrigerant.
Built to last
- ILTC control automatically manages the balancing of the compressors’ running times, thus enabling their service life to be extended.- Sealed refrigerant circuit : all the refrigerant components and pipe work are brazed, thus eliminating any risks of leakage. Pressure transducers replace the HP and LP pressostats, along with their capillary tubes (principal source of leaks).
Quick and easy installation at minimal cost
- Compact units taking up the strict minimum of ground surface area, for easy installation.- "Plug and Play" design with an integrated hydraulic module for minimising installation costs.- Perfect accessibility : easy access to all components, thanks to panels removable by screws, thus significantly reducing unit maintenance times.
Energy savings all year round
Thanks to ILTC control : - Providing intelligent management of the compressors’ running times.- In the majority of cases, obviating the need for a buffer tank for comfort air conditioning applications (2.5 l/kW).- Continuously monitoring and managing all the machine’s operating parameters.
Increased performance
- Optimal efficiency, thanks to the use of Scroll compressors with
General Specifications
Cabinet and structure
- Made of galvanised steel panels coated with oven-baked epoxy paint. Colour : RAL 9001.- For access to all components, the panels are removable by just removing the fixing screws.
Compressors
- Hermetically sealed, high output Scroll type compressors with a high Coefficient Of Performance (COP).- All models in the range equipped with compressors fitted in tandem for reducing both starting current draw and power absorbed under partial load conditions.- Excellent acoustic performance with extremely quiet operation and minimal vibration.- Robust and reliable Scroll compressor technology : Few moving parts (only 3), high tolerance to liquid pressure shocks, low starting torque, protection against excessive discharge temperatures.- Compressor motor cooled by intake gasses and equipped with automatic reset internal high temperature protection.- All compressors are mounted on anti-vibration pads in order to minimise noise and vibration transmission.
