Circulating-Water Temperature Controllers Have Single- or Dual-Zones
Due to a smaller heat exchanger in the Tempro Series, there is less circulating water. As a result, the preheating and cooldown periods are shorter, says the manufacturer. The product line includes Tempro plus D90, which is designed for temperatures up to 194°F (90°C). The open system has submersible pumps without pump seals. Tempro plus D140/160/180 models are designed for temperatures up to 284, 320 and 356°F (140, 160 and 180°C), respectively. The pressurized systems have magnetically coupled pumps for graduated temperature ranges. The dual-zone Tempro plus D250 is supplied with thermo-oil for processes to 482°F (250°C). Microprocessor control provides ±0.5°C accuracy. Other features include a touchscreen display, line evacuating for mold purge, and a sealless magnetically coupled pump.
