Products Temperature Controllers RMC Series Water Temperature Control Units

RMC Mold Temperature Control Units

Available in 2 models; designed for a better level of control and data.

The Mini-Aquatherm is similar to the Aquatherm but almost half the size.

Mini-Aquatherm RMC Series mold temperature controllers provide the best available components such as cast pump volute/heater tube/mixing assemblies, high flow pumps with leak-resistant silicon carbide seals and rugged Incoloy sheathed heaters for years of maintenance free operation. Each injection molding temperature control system comes with a large, user-friendly operator interface that provides a wide array of operational and diagnostic information.

RMC Family


  • 1/3 & 1/2 HP (.25 & .37 kW)
  • 3 kW and 6 kW heat range
  • High flow pumps
  • Leak-resistant, silicon carbide severe-duty pump seal
  • Long-life, low-watt density Incoloy heaters resist corrosion better than copper or stainless steel
  • Heavy-duty cast-iron pumps, heater tubes, and mixing tubes with O-ring seals reduce threaded fittings that can cause internal pressure losses and are prone to leaks
  • 24 VDC control circuit power
  • Tilted front panel angled for optimal viewing
  • Intelligent vent control - at start-up the automatic vent sequence deactivates when the mold circuit is above 120°F to avoid cooling of the mold after temporary power interruptions
  • Adjustable deviation alarm time delays
  • Supply and return temperature display
  • Solid top protects motor from dirt or fluid contamination
  • Four swivel casters for easy movement
  • Lifetime pump/heater casting warranty
  • Lifetime pump seal warranty
  • 3 year parts, 3 years labor
