Reliable Screw Compressor

• Carrier’s own ‘06T’ semi-hermetic screw compressor with direct driven motor
• Variable capacity slide valve
• Oversized bearing and suction gas cooled motor
• All components are easily accessible on site – minimized down time
• Patented line-design rotors and microprocessor control – guaranted accurate refrigerant meshing & enhanced service life

Compact Foot Print

• 1.0 m ~ 1.2 m width – easy through standard doorway
• Saves plant room space – reduces investment
• Best choice for new construction and retrofit projects

Auto Adaptive Control

• Automatic compressor unloading in case of abnormally high condensing pressure
• Patented control algorithm preventing excessive compressor cycling

Quick & Easy Installation

• Simplified electrical connection
  • Main disconnect switch with high trip capacity
  • Transformer to supply integrated control circuit
• Simplified hydronic connection
  • Victaulic connection on evaporator & condenser
  • 2 pass design – Inlet/Outlet on same side
  • Only electrical wiring & piping connection needed at site

Safe Operation

• Reversal/phase loosing protection
• Compressor protected against thermal overload, high pressure and low oil pressure
• Automatic compressor unloading in case of excessing condensing temperature
• Protection against current imbalance and electrical overload
• Low chilled water temperature protection

Exceptional Endurance Test

• Partnerships with specialised laboratories and use of limit simulation tools (finite element calculation) for the design of critical components
• Transport simulation test in the laboratory on a vibrating table and then on endurance circuit

Economizer System

• Economizer system with EXV permits considerable increase in cooling capacity and contributes to optimized efficiency
• Electronic expansion valve (EXV) allows operation at lower condensing pressure and improved utilization of evaporator heat exchange surface (superheat control)

Efficient Heat Exchanger

• High efficiency flooded evaporator
• Inbuilt electronic flow switch
• Auto setting basis cooler size and fluid type

Multiple Circuit Design

• Independent refrigerant circuits
• Independent electrical circuits

Environmentally Sustainable

• HFC-134a refrigerant
  • Refrigerant of the HFC group with zero ozone depletion potential
• Leak-tight refrigerant circuit
  • Reduction of leaks as no capillary tubes and flare connections are used
  • Verification of pressure transducers and temperature sensors without transferring refrigerant charge
