1.General Description: The Electricity Heating Thermal Oil Heater is an efficient low-pressure hightemperature heating equipment, which uses electricity as heat source and heattransfer oil as heat carrier,passing thermal energy to the heat users throughthe forced circulation of the hot oil pump,and returns to the Heater forreheating and recirculation.
2. Product features and uses:
2.1 Product features: (1)The Thermal Oil Heater can provide higher process temperature (≤300 degree)under lower pressure to replace the high and medium pressure boiler to heat.Compared with the steam boiler, the electric heating boiler needs lowerpressure, which will greatly increase security, improve the workingenvironment, reduce labor intensity and the one-time investment and have nopollution.It has the sensitive electronic automatic temperature control systemto provide reliable high precision, uniform heat transfer and good processperformance. (2)The Thermal Oil Heater has compact structure, small size, light weight,small footprint and simple installation.It is the new generation of heatingequipment in modern light industry, chemical and other industries. (3) Its temperature regulation is accuracy and reliable, equipped withtemperature, liquid level, the security alarm device. (4)It has high thermal efficiency (≥90%).
2.2 Uses: This series of Thermal Oil Heater can be used in the following industries: (1)Petroleum and chemical industry: polymerization, condensation, distillation,dehydrogenation, forced insulation. (2)Oil industry: fatty acid distillation, oil decomposition, concentration,esterification, vacuum deodorization. (3)Timber industry: multi-plywood, fiberboard, hot press molding, wood drying. (4)Building materials industry: gypsum board drying, asphalt heating. (5)Textile industry: heat setting,drying, hot melt dyeing. (6) Food industry: baking bread, biscuits. (7)Plastics and rubber industry: calendering, extrusion. (8)The Thermal Oil Heater is widely used in light and pharmaceutical industriesproduction.
3. Working principles: WDR series Thermal Oil Heater uses the heat transfer oil as heat carrier.Theheat transfer oil in the Heater body is heated to the desired temperature bythe electric heating elements, then is transported to the relative devices bythe hot oil pump to pass thermal energy.At last the oil is transported back toreheat to make a continuous heating process.
4. Basic structure:
The whole complete set of thermal oil Heater consists of the heating system,the circulation system, the electronic control system and the expansion system.
4.1The heating system: the main component is the electric heating oil Heater,it consists of the heating pipes, inlet and outlet oil pipes, frame, diversiondevices, protection cover.
4.2 The circulation system: the filter, high-temperature oil pump, oil Heaterpipe, valves and heat-demanding equipment constitute a closed loop.
4.3The expansion system: It mainly consists of the housing body, expansionpipe, overflow pipe, exhaust pipe, sewage outlet pipe, plate level gauge andfloat level controller. Its role is to accept the expansion oil, to compensatethe circulatory system, to supercharge,exhaust, alarm oil level and spill oil.The volume of the expansion slot can be configured according to user's requirements.
4.4 The electronic control system: the electrical control cabinet is the mainoperation control part of the Thermal Oil Heater,and it plays a very impoertantpart in starting pump, heating(stopping) temperature, controlling temperature,displaying temperature and liquid level alarm.
