Air condenser: - All aluminum micro-channel heat exchanger (MCHE) with high corrosion resistance. The all aluminum design eliminates the formation of galvanic currents between aluminum and copper that cause coil corrosion in saline or corrosive environments. Evaporator: - Carrier designed ﬂooded evaporator with mechanically cleanable water tubes - Electronic paddle-free ﬂow switch to ensure prompt alarm in case of poor liquid ﬂow rate - Thermal insulation with aluminum sheet ﬁnish (option) for perfect resistance to external aggression (mechanical and UV protection). Refrigerant circuits: - Two independent refrigerant circuits to secure partial cooling, if one of the two develops a fault. Auto-adaptive control: - Control algorithm prevents excessive compressor cycling (Carrier patent) - Automatic compressor unloading in case of abnormally high condensing pressure. If condenser coil fouling or fan failure occurs, the AquaForce continues to operate, but at reduced capacity. Exceptional endurance tests: - To design critical components subassembly minimising risk of failure on site, Carrier uses specialised laboratories and advanced dynamic simulation tools. - To ensure that the units reach customer sites in the same shape as they are when tested in the factory, Carrier tests the machine behavior while being moved along a 250 km trial. The test is based on a military standard and equal 5000 km by truck in a normal road. - To ensure coils corrosion resistance, salt mist corrosion resistance test are performed in Carrier's laboratory. In addition, to secure the same performance level is kept along the years and to optimise maintenance costs, with “CARRIER CONNECT” the end-user access to most-qualiﬁed remote monitoring services.
Standard unit features include: - Discharge dampers integrated in the oil separator (Carrier patent) - Silencer on the economizer return line - Condenser coils in V-shape with an open angle, allowing quieter air ﬂow across the coil - Low-noise IV generation Flying Birds fans, made of a composite material (Carrier patent) which do not generate intrusive low frequency noise - Rigid fan mounting preventing start-up noise (Carrier patent). Multiple options are available to further reduce the global sound level up to 6 dB(A).
Easy and fast installation
Simpliﬁed electrical connections: - Main disconnect switch - Transformer supply to the integrated control circuit (400/24 V) - Single electrical point of connection (optional for sizes 800 to 1150) - Factory installed main disconnect fuses (optional for sizes 600 to 1150). Simpliﬁed water connections: - Victaulic connections on the evaporator - Practical reference marks for entering and leaving water connections - Possibility to choose different evaporator conﬁgurations, 1 or 2 passes. Fast commissioning: - Systematic factory operation test before shipment - Functional test for main components, expansion devices, fans and compressors.
R134a: HFC refrigerant with zero ozone depletion potential 30% less refrigerant charge: The micro-channel technology used for condenser coils optimises heat transfer while minimising the refrigerant volume Leak tight refrigerant circuits: - Reduction of leaks as no capillary tubes and ﬂare connections are used - Veriﬁcation of pressure transducers and temperature sensors without transferring refrigerant charge - Discharge line shut-off valve and liquid line service valve for simpliﬁed maintenance. Refrigerant leaks alarm: Available as an option, this additional dry-contact allows reporting of possible leaks. The leak detector shall be mounted (at customer care) where, refrigerant leaks most likely to happen . Contact Carrier for more details.
Minimised operating sound levels
The Greenspeed® Intelligence, featuring variable-speed screw compressors and condenser fans, minimises noise levels at part load operation. At ESEER conditions for example, noise at 25% load is up to 10 dB(A) lower than noise at full load.
