Comparison of SMT SCOD vs. Commercial Chillers


 Chiller Base Frame — SMT SCOD vs. Commercial Chiller Unit:

  • Smartech SCOD: 12 gauge formed channel steel base, hot dipped galvanized and powder-coated.
  • Base is designed for six-point lifting connections. Offers 6” or 8” hot dipped galvanized I-beam base designed for four-point lifting connections.
  • Commercial units: Typically, 16-gauge sheet metal formed into channel.
  • Smartech features a stronger, more corrosion-resistant frame for your chiller.


Chiller Frame Pieces and Paneling:

  • Smartech SCOD: 12-gauge sheet metal tubular supports, 16-gauge condenser frame pieces,
  • 20 gauge panels.
  • Commercial units: 22-26 gauge panels, 20 gauge bent form supports.
  • Smartech pieces last longer and work better.


Compressor — Smartech SCOD vs. Commercial Chiller Comparison:

  • Smartech SCOD: High efficiency Scroll compressor available in single or tandem configuration, with internal motor protection, suction & liquid line service valves. Optional NO Tandem scroll sets for more reliable and service-friendly construction.
  • Commercial Chiller Specs: Standard offering is multiple tandem scroll compressor sets. A single compressor failure can destroy all compressors in the tandem set. Scroll compressors are not serviceable/repairable.
  • You may not want to risk having your chiller unit fail because of one compressor breakdown. Smartech’s SCOD is designed with a single compressor configuration option to give you added redundancy and reliability.


Smartech Evaporator vs. Commercial Evaporator Comparison

  • Smartech SCOD: Brazed plate evaporators with option of shell & tube evaporator
  • Commercial Chiller Units: Most feature brazed plate evaporators
  • Smartech gives you the flexibility of multiple evaporator options.


Smartech Air-Cooled Condenser vs Commercial Condensor Comparison:

  • Smartech SCOD: Super high efficient TEAO fan motors, inverter duty rated. Low-noise fan blades (as low as 66dBA). Non-lanced hydrophilic coated aluminum fins, 0.0055” thickness.
  • Maximum 14 fins per inch.
  • Commercial units: Lanced fins (difficult to clean and susceptible to clogging), 18-22 fins per inch (also increases chances of clogging), 0.0035” thickness.
  • Smartech gives you a quieter fan that is easier to clean.


Smartech Electrical Companent vs Commercial Electrical Component Comparison:

  • Smartech SCOD: Non-proprietary Chiller microprocessor featuring free windows based software. Capable of communicating with Bacnet IP, Bacnet MSTP, Ethernet, Johnson N2, Modbus, Modbus Plus, and Lonworks.
  • Circuit breakers for compressors and branch circuit breakers on condenser fans. Individual contactors for all motors. Hard wired overloads on all motors.
  • Circuit breakers for both primary & secondary sides of transformer. Under/Over voltage relay & phase monitor on all units. All wiring run in sealtite conduit inside rigid raceway.
  • Commercial units: Proprietary controller, basic motor controls, with or without fusing on primary/secondary transformer.
  • Smartech’s electrical system is flexible enough for any situation.


Available Options for Custom Smartech Process Cooling Systems:

  • NRC-rated Smart Advance2 micro-controller
  • Stainless steel shell & tube evaporator
  • Stainless steel or 90/10 Cupro-Nickel Condenser
  • Stainless Steel base and/or sheet metal
  • Integrated SS Pump package with or without SS process tank
  • Low-temperature applications to 0F LFT and other custom applications welcome.
