Combustible gas or a diesel burner can be configured as the heat source. The burner heats the thermal oil pipe, then the circulating thermal oil supplies heat to the production equipment.
Buyers may describe this equipment as a gas mold temperature controller, diesel mold temperature controller, gas thermal oil heater, thermal oil heating system or hot press heating system. Yigao reviews the same project around heat load, thermal oil circulation, fuel condition and installation layout.
The machine includes independent circulation and exhaust systems, making installation, disassembly and daily operation more convenient for factory use.
A 304 stainless steel waste heat recovery structure is intended to preheat burner intake air and reduce exhaust temperature. Actual fuel saving depends on load, fuel, exhaust settings, operating hours and test conditions.
Configuration groups can include heating circulation, waste heat recovery, exhaust, burner, control, gas leak relief, induced-draft and phase-loss protection systems.
The gas mold temperature controller is designed as a compact thermal oil heating system for hot press heating, reactor heating and other production equipment, with one-key start, PLC control, phase-loss protection, purge logic after ignition failure and explosion-protection configuration.
Custom configuration
Yigao can customize the gas-fired mold temperature controller around the customer's heat load, fuel condition, thermal oil circuit and factory installation space.
Please send target temperature, heating load, preferred fuel type such as natural gas, LNG or diesel, thermal oil medium, mold or machine size, pipeline distance and equipment drawings.
Ordering information
For custom heating equipment, commercial terms and document scope are confirmed after the technical configuration, quantity and destination requirements are reviewed.
Buyer FAQ
Gas or diesel-fired thermal oil heating can be considered when the required heat load is high, the production schedule is continuous and local fuel cost is favorable. The operating-cost difference should be calculated from project heat load, fuel heat value, system efficiency assumption, local tariff and annual operating hours.
Typical applications include hot press production lines, reactor heating, composite laminating, large molds and other equipment that requires circulating thermal oil temperature control.
Compare the required heat capacity, fuel heat value, electricity conversion, efficiency assumption, local gas or diesel tariff, local electricity tariff, hours per day and working days per year. Yigao can review the calculation with your process data before recommending a configuration.
ROI depends on the additional equipment investment and the calculated annual operating-cost difference. It should not be treated as a fixed payback period until the project heat load, energy tariff, operating schedule and installation scope are confirmed.
Gas-Fired Mold Temperature Controller is used for Reaction kettle heating, Foaming machine, Woodworking hot press, Drying kiln. Final selection should be based on the working medium, target temperature, capacity and installation conditions.
Yigao can customize the gas-fired mold temperature controller around the customer's heat load, fuel condition, thermal oil circuit and factory installation space.
Please send target temperature, heating load, preferred fuel type such as natural gas, LNG or diesel, thermal oil medium, mold or machine size, pipeline distance and equipment drawings.
MOQ and production lead time depend on the selected power, material, control system, dimensions, quantity and order-specific engineering work. Ask Yigao to confirm both items in the written quotation after the technical configuration is agreed.
Certification and test-document availability varies by model, components and destination market. State the required standard and destination country during inquiry, then ask Yigao to list the applicable documents in the quotation. Do not assume one certificate covers every custom configuration.
Yigao provides technical consultation and equipment coordination. The exact warranty, commissioning, spare-parts, remote-support and on-site service scope should be confirmed in the written quotation or contract for the selected configuration and destination.
