SRL/SRZType radiator

SRL/SRZA radiator is made of steam or hot water（130—70An air heater with a temperature of (℃) as the heat medium. Widely used in hot air heating and air conditioning systems.

SRL/SRZType radiator Caitong steel pipe wrapped with aluminum strip spiral finned tube.

SRL/SRZThe radiator adopts a steel pipe wrapped steel strip spiral finned tube.

SRL/SRZThere are two types of radiators37A variety, whose model is composed of pinyin and two sets of numbers.

surface air cooler

Cold water surface coolers can be used for wet cooling (cooling, dehumidification) of air: condensation water is precipitated during air cooling, while dry cooling (with constant moisture content during equal humidity cooling and air cooling) can also be used for heating air.

characteristic:

lAluminum rolled spiral ribs have a reasonable structure, advanced technology, good overall integrity and thermal performance, fundamentally eliminating contact thermal resistance and electrical corrosion phenomena.

lThe ribs of the ribbed tube are trapezoidal, smooth, and wrinkle free, making it easy to eliminate condensation water on the outer surface of the ribs during wet cooling,

lLabeling method for cooling surface coolers: model row number×Number of surface roots×Effective length of rib tube

Example:KL-1type2×12×1400Aluminum sheet cooling surface cooler1type2Row, the number of surface roots is12The effective length of the root and rib tube is1400mm.

Installation

1. The heater should be connected in a parallel manner, and after installation, it should be ensured that the heater is level, stable, and of reasonable height. The fan should be placed on the wall to maintain a certain space, greater than100mmJust enough.

2. The installation bracket or other related accessories used to fix the heater are not included in the heater product and should be provided by the user.

3. Diameter of the inlet and outlet pipes of the warm air blower（DN40～ DN80)

4. The inlet and outlet pipes can be connected using threaded or welded connections.

5. Valves should be installed on the inlet connection.

6. After adjusting the air outlet louver, use the ingot nut on the louver adjustment handle to fix it.

7. The power and voltage of the heater motor are shown in the chart380vThe wiring should be operated by a professional electrician.

8. Before powering on the fan for the first time, observe whether there are any foreign objects near the impeller and swing the impeller to see if there is any scraping or collision during rotation.

9. After the fan is powered on, observe whether the rotation direction of the impeller is correct, and determine whether the rotation direction of the impeller is correct based on the direction of the air outlet.

Instructions and precautions for use

1. The installation form is shown in the figure.

2. The heater should be matched with the corresponding heat medium pipeline system, and a shut-off valve should be installed on the return pipe of the heater. A venting device should be installed on the entire pipeline system.

3. The heat medium pipeline system must be cleaned before connecting to the heater, and a drain valve should be installed under each heater.

4. For the convenience of adjusting the water flow rate of each heater in the system, it is best to design the system in the same program.

5. GSThe temperature of the hot water used by the heater should be maintained at80linear measure-90Above the degree, not lower than75The water flow rate must be maintained using the water flow velocity in the heat dissipation pipe0.2rice/More than a second.

6. Use of warm air blower2-3After the year, apply chemical methods to remove dirt from the drainage pipes. To reduce scale, the heat used

Softening treatment should be carried out. During the heating season, the pipeline system should be filled with water to reduce corrosion.
