Frigel Thermogel – Standard Temperature Control Units (Standard TCU)
Thermogel Standard Temperature Control Units (Standard TCU) provide precise and stable regulation of process water temperatures up to 140 °C, increasing productivity, reducing scrap and improving product quality in injection molding, blow molding, extrusion and metal casting.
Thermogel temperature control units are designed for a wide range of industrial applications — from injection molding, blow molding and extrusion of plastics, to die casting, chemical and pharmaceutical processes. Precise temperature control leads to shorter cycles, reduced scrap, consistent high-quality output and better repeatability, while keeping operator involvement minimal.
What Is a Standard Temperature Control Unit (Standard TCU)?
Thermogel Standard TCU systems are designed for precise temperature control in water-cooled processes connected to external cooling systems (such as the ECODRY adiabatic cooler). Depending on the required temperature range, units operate with water up to 90 °C, pressurized water up to 120 °C or pressurized water up to 140 °C.
Main Components of a Thermogel TCU
Each Thermogel unit contains all components needed for stable and precise temperature control:
- Process pump sized according to application requirements
- Electric heaters matching maximum thermal load
- Heat exchanger for indirect cooling (TRP and TBX models)
- Proportional valve for regulating cooling water
- Microprocessor control panel for fully automatic operation
Operating Modes – Heating & Cooling
Thermogel TCU units operate in both heating and cooling modes, fully automatically:
- Heating Mode: Electric heaters raise and maintain the process water temperature as required by the mold or process.
- Cooling Mode: Heat is removed to the external cooling system — either directly or via a heat exchanger, with precise regulation of cooling water flow.
This ensures stable temperature control during machine startup and throughout continuous production.
Thermogel Standard TCU – Product Overview
The Thermogel Standard Temperature Control Unit line consists of three main models: TRP (indirect cooling, pressurized water up to 140 °C), Thermogel 120 TDK (direct cooling, pressurized water up to 120 °C) and Thermogel 90 TBX (indirect cooling, pressure/vacuum mode up to 90 °C).
Thermogel TRP – Pressurized Water up to 140 °C, Indirect Cooling
Thermogel TRP is a pressurized-water TCU for general applications in plastic and rubber injection molding, using a plate heat exchanger for indirect cooling. It is an excellent alternative to traditional oil heating units, offering simpler handling and lower maintenance costs.
