Flow Testing

 Flow Testing is one of our many services we offer to provide performance data for any given cooler type and core configuration. We can flow up to 3.1 litres per second and typically provide 5 flow rates from the maximum flow to a minimum. From these 5 flow rates we record the pressure drop at each point and present this with the unit in hard copy or electronically. 


Flow Testing is becoming more of a requirement especially as part of our Service Cleaning package as we record the history of an active Heat Exchanger throughout its working life, this allows us to monitor any changes in the performance of the unit as it progresses thorugh time.


The conditions of the testing are as follows,

1, Once the unit is recieved it will require a flush through to eliminate any contamination the flow rig.

2, If the unit is oil related a separate flushing process is required to remove all oil and contaminate deposits prior to flow testing.

3, We flow test at 55 degrees.

4, We use Deionised water for all tests

5, Our Flow Rig is fitted with 5 Micron Filter on entry and exit of flow. These filters are only engaged for a 5 minute period prior to the test and 5 minutes post test. They are not engaged during the actual flow test.

6, We run 5 flow rates through the core and flow until we have 5 flow rates ranging from a maximum to a minimum.

7, For each flow rate applied their is also a measure of pressure the drop in bar which is recorded per flow rate.

8, The data is then applied to a flow document and the unit id number is recorded along with the date and time of the test. Should the unit be tested again later on we can compare all previous results and determin the performance of the unit in its current condition.

9, Upon test completion each unit is Flushed, Nitrogen purged and placed in the oven until dry. (if the unit is part of a cleanse package it simply moves to the next stage in the process)

10, The unit is presented back to you with the data documentation in hard copy and is also available in Electronic form.
