ATT

Alternating Temperature Technology

Variotherm temperature control used in combination with
suitable mould inserts allows variations in temperature of more
than 100 °C in critical areas or in complete moulds. In order to
achieve this, the SINGLE ATT system operates with two separate
circuits that contain thermal fluid with a different temperature.
Both ATT circuits contain the same fluid. Water is recommended
for temperatures of up to 200 °C, while oil is suitable for applications that operate with temperatures of up to 300 °C.

Areas of application
▸ Injection moulding of thermoplastics
▸ Production of components made from fibre-reinforced composites
▸ Other cyclic processes with temperature profile
Standard equipment
General

SINGLE ATT ‘Alternating Temperature Technology’ is an individually configured system
solution for liquid-operated variotherm temperature control of injection moulds, compression moulds and other mould types. As the active system fills moulds alternately with warm
and cold thermal fluids, it can actively heat or
cool processes in defined alternation.

▸ Temperature control system with one heating and one cooling
circuit and circuit switch
▸ Fast alternation between heating and cooling circuit thanks to
hydraulic switching
▸ Energy-saving temperature-controlled feeding of return fluid
into the corresponding circuit
▸ Easy operation with touch screen
▸ Connection to standard moulds
▸ Rugged, powder-coated steel sheet housing
Hydraulics
▸ High-quality materials and reliable components
▸ Wear-free flow metering and flow monitoring
▸ Hose connections between system and valve station
