(15) The NRD-550 Series models are non-refrigerated heat exchange systems which utilize a tap or building water source to remove heat from your process. They are particularly useful in situations where the cooling water source temperature is too low, or where the pressure and cleanliness of the water may cause damage to the equipment or compromise performance. An internal plate-type heat exchanger is used to remove heat efficiently while isolating the cooling and process loops. Large quantities of heat can be removed in a small physical size as compared to refrigerated models. Our modular frames are used to package these systems in order to ensure the smallest possible footprint.
(7) Tek-Temp Instruments, new FK Series recirculating heat exchangers remove heat from process liquids directly to the ambient air by means of a radiator and fan. Ideal application conditions are when the desired circulating temperature is significantly higher than the ambient air temperature, and/or when the heat load is relatively small. Cooling capacity is dependent on the process liquid flow rate, and the difference between the circulating and ambient temperatures. Positive displacement and centrifugal-type circulating pumps are available and are rated for continuous operation.
