Yuanda Thermal oil boilers
> Gas/Diesel Thermal Oil Boiler
Horizontal or Vertical type, Automatic thermal oil boiler with burner (brand of baltur, riello, unigas, ecoflame, oilon, etc.)
Structure:
YY(Q)W thermal oil boiler adopts a horizontal chamber-fired three-coil structure, and the body is composed of an outer coil, a middle coil and an inner coil.
Whole System
including oil heater boiler proper, burner, control cabinet, oil expansion tank, oil storage tank, oil circulating pumps, economizer, chimney, pipes, valves, gauges, etc.
> Electricity Thermal Oil Boiler
The equipment Use electricity heating thermal oil, automatically heating oil up to temperature 200°C-350°C. Widely used in asphalt, bitumen, textile, plywood hot pressing, reactor, food fryer, packaging industry, refinery oil, etc

Electric heating thermal oil heater consists of the main parts (including electric heater host , high-temperature oil pump and Y-shape filter), expansion tank, control cabinet and piping. All the components of the system must work together in harmony for proper performance.
> Coal/Biomass wood thermal oil heater
Horizontal type thermal oil boiler, use chain grate for automatic feeding, high efficiency, environmental-friendly.

Boiler Features

Compace coil tube structure
Horizontal chamber combustion three coil structure, its body is composed of outer coil, middle coil, inner coil and rear coil.
Wet back sturcture
Unique design for heating surface in end of boiler, somke chamber wet back sturcuture, make lower heat loss, improve thermal efficiency 2%-3%.
External oil tank
The design of the external oil collecting tank prevents the slow flow of grease carbonization and avoids accidents.
100% safety runing & best insulation
Double layer 12cm aluminum silicate insulation. Sealed tightly to avoid air leaks. Over oil temperature/over smoke temperature/low flow alarm.Technical Parameter
