1. Product Description

YY(Q)L series of horizontal and YY(Q)W series of vertical gas (oil)-fired thermal fluid ("hot oil") heaters are used in many industrial applications where efficiency and accurate temperature control between 100°C and 350°Care 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 high temperature goes into the heat-required equipments, like dryer, and then comes back to the heater and is 
re-heated again. The outside insulation is aluminium silicate fibrofelt with thickness of 100-150mm. 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 and safety interlock system
2.1 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.
2.2 Control points of gas-fired heater (Basic requirements)

b. System early warning (EW) and alarm (AL) for shutting down the heater

1	Fluid outlet high temperature	6	High smoke temperature
2	Low fluid flow rate	7	High temperature of combustion air
3	Low fluid level of expansion tank	8	Flame fault (Interlock to burner)
4	Low pressure of inlet/outlet of fluid	9	Low pressure of combustion air (Interlock and burner)
5	Gas/oil leakage (Interlock to burner)	10	Pump fault and blower fault (Interlock to burner)

 
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 heater. 
e. Accurate temperature control.The oil temperature can be controlled within ±1°C.                        
f .The compact structure can cover a small working area.
g. Easy to install, operate and maintain.
