On-site heat treatment in large-scale installation projects, due to
harsh environmental conditions,Pre Heat Treatment Inverter Power Sources
PWHT and often lack of maintenance technology and accessories,
according to this feature we designed and produced a versatile ZWK
temperature control box. ZWK uses temperature program control
instrument, using microprocessor technology , software configuration,
PID parameter self-tuning, each time you use to find the adjustment
parameter value, and automatically enter the memory. The voltage
regulation adopts the integrated voltage regulation module, the three
phases do not interfere, the output voltage is 0-220V, and the thyristor
adopts high-power two-way thyristor, and the output capacity is large.
The machine can be set and operated according to different process
temperature curves. The temperature is automatically recorded, which can
not only improve product quality, but also extend the life of the
heater. It can be matched with heaters of different voltages for
preheating and welding before welding. Post heat treatment. Output
(0-220V) adjustable voltage.
