1. Product Description

YY(Q)W series of horizontal oil (gas) fired thermal fluid (hot oil) heaters are used in many industrial applications where efficiency and accurate temperature control between 100 º C and 350 º C are required. They work in a way of heating directly thermal fluid in the pipes with the high temperature smoke. With the help of forced circulation oil pumps, the fluid with low temperature will come back to the heater from the heat-required equipments (like dryers) and is re-heated again. The shell plate is made of Q235-A/B steel plate. The outside insulation is aluminium silicate fibrofelt with thickness of 150mm. The heater is packed by 0.5mm stainless steel sheet. OLYMSPAN has many years experience in this field and we offer can a broad range of products, service and support.

2. Automatic control, instruments and safety interlock system

2.1 Automatic control system
The instruments and natural gas transmitter are offered in whole sets. We must guarantee the integrity,
Safety and reliability of the control system.

2.2 Functions achievement (Basic requirements)
A. A steady and high temperature is offered and meets the requirements of load.
B. Automatic load regulation is achieved.
C. Safety interlock and feedback protection are achieved in the abnormal conditions.
D. Early warning, alarm, fault display and locking are achieved.
E. Continuous and steady working is achieved.
F. Manual and automatic working can be achieved as customer's requirement.

2.3 List of control functions (Basic requirements)
A. Flow detection: A flow meter is fixed at the outlet pipe to show the fluid flow rate. The alarm and interlock to
Blower and burner happens against the abnormal flow rate.
B. Pressure detection: Pressure transmitters are fixed at the inlet and outlet pipes to show the pressures.
The alarm and interlock to blower and burner happens against the abnormal pressures.
C. Temperature control: Reading and regulating temperature are achieved at the main outlet pipe. The alarm
And interlock to blower and burner happens against the abnormal temperature.
D. Multi-point temperatures display: Temperatures are read at inlet and outlet fluid pipes, smoke duct,
Air pre-heater and so on.

3. Product Features
A. High thermal efficiency, unique structure, general thermal efficiency can reach 90%.
B. The proprietary combustion technology and the structure of heating coiler can absolutely avoid the overheat
And damage of coilers in common use conditions.
C. The top of inner coiler is designed into cone-shape, which can prevent the casting material on the top fall off
In high temperature.
D. When abnormal conditions happen, safety interlock system starts up to protect the boiler.
E. Accurate temperature control. The oil temperature in the outlet can be controlled within ± 1 º C.
F. The compact structure can cover a small working area.
G. Easy to install, operate and maintain.
