Precision Temperature Control

Two Loop Chiller for True Process Applications

The PT Model Chiller Uses Two pumps with one process tank. One pump circulates coolant through the evaporator to maintain a constant tank temperature, while a second pump circulates coolant from the process tank (on-board chiller) through the process and then back to the process tank.

Closed Loop Chiller Flow Schematic
Click image for larger view.

The PT Model Chiller Uses Two pumps with one process tank. One pump circulates coolant through the evaporator to maintain a constant tank temperature, while a second pump circulates coolant from the process tank (on-board chiller) through the process and then back to the process tank.


These are a few of our basic options. Click the button below to see all chiller options.

CTC: Digital Temperature Controller: Provides close temperature control (±0.5°F). Displays bot set-point and coolant temperature.

ATC: Ambient Tracking Controller. A dual input digital tempertue controller allows the coolant temperature to track ambient temperature at a constant, adjustable differential. Displays both ambient and coolant temperature.

OP: Optional Pumps. A variety of pumps are available to meet almost any flow and pressure requirement for both water and oil-based coolants.

LF: Low Flow Interlock. Prevents damage to machine on loss of flow.

HT: Temperature Fault Interlock. Indicates coolant temperature is out of range.

ILH: In-Line Heater. Warms up coolant to optimum operating termperature.

ILF: In-Line Filter Insures clean coolant.

PS: Pure System. Coolant only comes in contact with stainless steel or plastic.

Non-Copper. Oil only comes in contact with iron or stainless steel.

NRCW and NRCA: Non-Refrigerated Cooler. Uses central chilled water or ambient air instead of refrigeration. Saves space and maintenance.

W: Water-Cooled Condenser For use with tower or city water. Removes heat from the work area while saving space and maintenance.

TURMOIL COOLER FEATURES

Heavy-Duty Construction. Coolers are designed for continuous industrial duty and dependable long life. Welded steel cabinet features lifting eyebolts and mounting skid. Panels are easily removable for complete access.

High-Ambient Condensers. Oversized to run cool in hot, dirty environments. All condensers are protected with a cleanable aluminum air intake filter.

Ozone-Friendly Refrigerants. Turmoil coolers use only approved, non-ozone-depleting refrigerants. HFC-134a refrigerant is standard on all models with up to 3 HP compressors and optional on all larger models. HCFC-22 refrigerant is standard on all models with 4 HP compressors or larger.

Complete Temperature Control. Choice of analog or digital controllers available with options to hold coolant within ±0.5ºF (±0.25ºC) of set-point. Hot gas bypass unloading eliminates compressor short cycling.

Super-Efficient Evaporators. For both oil- or water-based fluids. Brazed plate, immersion coil, or shell-and-tube design of stainless steel, copper, or steel construction depending on application. Tested for 350 PSI working pressure.
