Some of the unique features that make our coolers much better than others in terms of operation, performance and maintenance :
1. In-built safety relief valve to prevent accidents in the field in case of an (unlikely) event of coil failure. This kind of failure may occur due to chloride attack & stainless steel fails under this attack. It is always advisable to therefore have a built-in shell relief valve for human safety.
2. Coils with double helix shape for more heat exchange
3. Counter flow technique of the sample and the cooling water, which ensures that the sample & cooling water flow in opposite direction, thus resulting in effective cooling of the sample
4. Sample coils made of SS-316 and shell made of SS-304, which is best, suited for normal cooling water conditions. If the chloride content in the cooling water is above 35 ppm, other coil materials are also available such as Monel / Inconnel etc.
5. An association with the IIT for calculating and testing the performance, heat calculations and efficiency of our sample coolers. Sample cooler performance is validated by IIT – Powai / Kharagpur
6. We can offer IBR approved sample coolers as well, as our facilities are approved by IBR
7. The DHx series design which incorporates design suggestions given by IIT, is better in terms of saving in cooling water consumption
8. Sample coils are easy to replace, as they are not welded to the top flange. This also provides easy maintenance of the cooler. With the presence of a drain plug at the bottom of the cooler, flushing out of cooling water and cleaning the cooler is effective and easy
