    FORM QTC3-EG6 (1118) Introduction Quantech™ is proud to present the Model QTC3 Air-Cooled Scroll Chiller. FEATURES AND BENEFITS Installation The QTC3 chiller arrives as a factory-assembled package ready to be installed outdoors, either on the roof or at ground level. The air-cooled condensers eliminate the capital, installation and maintenance costs of a cooling-tower circuit.
  • Page 6 30%, the QTC3 chiller provides the most ecologically friendly equipment. Part- nered with its low-sound properties for noise pollution prevention, this chiller is a true earth-friendly offering. QUANTECH...
  • Page 7 The condenser heat exchangers are light enough that no crane is required for replacement. And when it’s time to clean them, city tap water, with water pressure typical of a spray from a common garden hose, is all that’s needed. QUANTECH...

    The compact, high efficiency Brazed Plate Heat Exchanger (BPHE) is constructed with 316L stainless steel corrugated channel plates with a filler material between each plate. It offers excellent heat transfer performance with a compact size and low weight, reducing structural steel requirements on the job site. QUANTECH...
  • Page 9 The evaporator is equipped with a thermostat-controlled heater. The heater provides freeze protection for the evaporator down to -20°F (-29°C) ambient. The evaporator is covered with 3/4” flexible, closed-cell, foam insulation (K=0.25). A factory-wired flow switch is standard, installed in a pipe section at the outlet of the evaporator. QUANTECH...

  • Page 17 Enclosure Panels (Unit) – Tamperproof enclosure panels prevent unauthorized access to units. Enclosure panels can provide an aesthetically pleasing alternative to expensive fenc- ing. Additionally, for proper head pressure control, Quantech recommends the use of Con- denser Louvered Panels for winter applications where wind gusts may exceed five miles per hour (8 kph).

  • Page 54 VARIABLE PRIMARY FLOW Quantech recommends a maximum 10% per minute flow rate of change, based on design flow, for variable primary flow applications. Eight to 10 gallons per chiller ton (8.6 to 10.8 liter per cooling kW) is recommended for the system liquid volume. Insufficient system volume and rapid flow changes can cause control problems or can even cause chiller shutdowns.
