| DRK air electric heater |
DRK
air electric heater is a complete device by means of conversion
from electric energy to thermal energy with advantages of convenient
supply of energy, compact structure, automatic control of temperature,
convenience for installation and maintenance and no pollution, etc.
This
heater consists of tube container and electric heating element complete
with temperature control cubicle (console). The heating element
employs Cr18Ni19Ti stainless and seamless steel tube as its protective
bushing, and the internal heating element is composed of OCr27Al17M02
high-temperature resistance wire and crystalline MgO. The temperature
control is regulated by controllable silicon with PID digital display.
In the range under control temperatures can be freely set as required
and the constant temperature is automatically maintained. The temperature
is controlled within ±5℃ with out-of-limit sound and light alarm
and multiple protective functions, and can be controlled locally
or remotely.
