TCF Series Centrifugal Compressor Chillers

TCFW375 - Single Circuit Chiller 50 ton (Ice Rink Chiller

TCFW350 - Single Circuit Chiller 100 ton

Thermal Care has expanded its line of industrial TCF central chillers to include the TCFW375 ice rink chillers. TCF central chillers combine the efficiencies of both a hybrid film evaporator and a Turbocor variable speed centrifugal compressor to deliver optimum full and part load efficiencies. The result is one of the most energy efficient central chillers ever built.

Overview

  • Water cooled single circuit model
  • Advanced PLC System maintains stable and reliable operation of the chiller
  • Hybrid film evaporator for the most efficient heat transfer
  • Direct-drive variable-speed Turbocor centrifugal compressor technology continuously adjusts speed to match load and reduce operating costs
  • C-UL 508A listed and labeled industrial control panel
  • Rotary circuit breaker for compressor
  • Single point connection for electrical hookup at control cabinet
  • Only one major moving part - the compressor impeller which is used to compress gas and provides the highest full load efficiency and less energy use.

Integrated Variable Speed Drive Motor Control

  • Enhances temperature control capability for partial load performance.
  • Soft-start control reduces peak energy demand and extends motor life by lowering initial current inrush at start-up
  • Lowest noise level; whisper quiet sound levels with 74 dBA and virtually no structure-born vibration

Magnetic “Friction-Free” Bearings

  • Equipment life is extended since there is no contact with surfaces as the shaft rotates
  • Compressor senses a power failure as a normal shutdown. Internal capacitors and rotational
    energy allow the motor to become a generator and provide a fail-safe shutdown.
  • Compressor shaft rests on a graphite-lined touchdown bearing when not in operation

Oil Free Operation

  • Eliminates oil management system and all related maintenance costs
  • No potential oil contamination of refrigerant
  • No compressor failure due to oil contamination
  • Lower energy required can save up to 40% in annual operating costs when compared to screw-type compressor

Integrated TCF PLC Control

  • Adaptive control maximizes operational performance
  • Provides extensive sensing capabilities and monitors compressor bearing and shaft positions six million times per minute
  • Communications package allows for remote diagnostics of the chiller
  • Built-in 24 VDC control circuitry

TCFW375 Additional Features

  • Modular expansion to over 300 tons using up to six chillers
  • Unit has a slim footprint and can fit through a 34” opening
  • Turbocor TTH375 highlift variable speed centrifugal compressor with oil-free, magnetic bearings is ideal for ice rinks
  • R513A Class A refrigerant features low toxicity and low flammability
  • Lower Global Warming Potential (GWP)* - Featuring OpteonTM XP10 (R-513A) Refrigerant
