Flue Leakage Testing
Airtherm Ltd now provide pressure testing of all types of flue and exhaust systems fully in accordance with IGEM/UP/10 Edition 4.
All of our flue products are factory tested to ensure they are suitable for the pressure rating of the appliances we fit our systems on. Once our systems are installed we can offer pressure testing to further prove the integrity of the products, whether it is for a H1 rated (5000pa) appliance for combined heat and power unit, generator sets orP1 (200pa) for lower pressure usage on boilers, biomass boilers, hot water generators and Class 1 prefabricated chimney’s.
The Wöhler DP 600 features a wide measuring range of the volume flow. Two different adapters are necessary to guaranty the specified accuracy of the volume flow measurement.
The Wöhler DC 600 has a colour display with a diagonal of 6 cm. The OLED-technology allows reading the display from almost any angle of view. The Wöhler DP 600 is operated using four multiple function keys.
The Wöhler DP 600 controls the tightness of exhaust ducts and chimneys. A menu enables the user to select between the different installation classes. The Wöhler DP 600 regulates automatically the pressure which is necessary to control the flue gas systems classes P, H and N and determines the leakage rate automatically.
The seal on the flue/ exhaust gas systems is measured by inflating the line to a constant overpressure and measuring the volume flow required to maintain the overpressure. The following diagram shows the principle of the measurement configuration. The volume flow generated by means of two turbine blowers is fed into the sealed exhaust gas system by means of a hose. As a result of incoming air, the pressure in the exhaust system rises. This pressure is fed back to the measuring device via a second hose. The turbine blowers are regulated bycomparing the pre-set test pressure with the actual test pressure in the exhaust gas system.
- Tightness testing with leakage rates up to 200.00 m³/h
- Tightness testing of all chimney classes and flue gas systems
- Tightness testing of flue gas systems of combined heat and power plants
- Confirmation of a sufficient combustion air supply according to TRGI sheet G 625 (simple and
- detailed procedure)
- Stove tightness testing
- Tightness testing is also possible with negative pressure
Advantages to using a testing device.
- The terminal can be sealed from the ground using a specialist bladder – ideal if roof access is difficult.
- There is no need to have access to other floors
- Eliminates the possibility of human error.
- A print out of the result is produced and signed by the tester.
- The BSEN 1443 is the only recognised method of testing in many European countries, smoke integrity tests are not allowed.
- This service is usually very
- quick and gives you assurance.
