Product description
The PRO RP 245 E is a compact circulating process thermostat designed for external applications requiring rapid temperature changes and precise control. Low filling volume and an integrated cooling coil enable fast thermal response. The unit features a stainless steel bath, pressure-suction pump and hybrid cooling (air and optional cooling water). Detachable command console and modern interfaces allow remote operation and integration into laboratory or production systems.
