Cab Leakage Tester

Cab Leakage Tester

THE CLASSIC CAB LEAKAGE TESTER

The Cab Leakage Tester is designed to allow a user to balance and commission mechanical / vehicle ventilation & exhaust systems with confidence.
The CLT (Cab Leakage Tester) works by pressurizing, or depressurizing, the Volume Under Test to a specified pressure, and measuring the air volume flow generated to produce a leakage rate, or equivalent body hole size.
Our CLT can generate up to a maximum 400l/s of airflow over the 5 different nozzle sizes ranging from 15mm to 153mm in diameter. It is a primary measuring device and is the most accurate method of measuring the air leakage rate of the Volume Under Test.
As of 2015, all CLTs are manufactured with our new Instrument Pod, the MKII Control Pod. All existing CLTs can benefit from this new control system with the purchase a replacement pod, or will have the option of receiving this new control pod with a full CLT refurbishment.
We also offer the facility to design and manufacture a bespoke cab leakage tester to suit your specifications. Contact Us directly, with your requirements, and we will be more than happy to provide you with a quotation.

[ – ] More Info

The new CLT POD MKII has been designed to be intuitive to use and also very stable. Using all new technology and software, the new control pod is a marked improvement over the original control pod. It is also much lighter and smaller provides both Manual and Automatic test modes as standard.
The MK II Pod makes use of an easy to use 5 Button Keypad and a graphic LCD to provide the user with much more user friendly interface. It has a USB port that will allow you to stream data in real time to a connected computer.
