Our thermal design team analysed the rocket exhaust process data and then designed a specialty heat exchanger to meet the Rocket Lab design brief.  As result, Pressure Worx specially developed a number of notable features for the exhaust condenser.  We included a condensate impingement separator and collection sump within the exhaust outlet bonnet.  “We had to analyse over 29 different and complex rocket operating cases to come up with a heat exchange solution that would meet all of them”, said Rowntree.

Following the successful design and delivery of the Rocket Exhaust Condenser, Rocket Lab asked us to design and supply a Spray Chamber Vessel, also fitted to the exhaust.  This vessel saturates the exhaust and cools the stream prior to the rocket exhaust condenser.  Furthermore, it works under vacuum and was fabricated entirely from stainless steel.

“We loved working with the engineers from Rocket Lab and its awesome to be involved in just a small way with helping develop their test facility to enhance their rocket performance for future missions into space. They are an innovative and exciting company, proud of their New Zealand origin”.

Different products and processes require different types of CIP systems. Single use and dump systems are often installed where there is a large amount of fouling due to product deposits and high chemical oxygen demand (COD) levels make them unsuitable for re-use systems. Reuse CIP systems typically have a dilute chemical supply tank and a post rinse recovery tank used for the next pre-rinse. Both types of systems require critical temperature control to prevent product spoilage and to increase its dirt removal efficiency.

At Pressure Worx, we understand both the process of CIP systems and the requirements of the heating systems for CIP temperature control for water and cleaning agents. We custom design heat exchangers and heating systems with either an in-line heater for each cleaning circuit or a re-circulated kidney type heater for each chemical supply tank or water recovery tank. In both cases, the cleaning agents will be heated to the proper temperature.

Capacity and pressure requirements in CIP systems vary dramatically, so we custom design heat exchangers for your specific CIP system requirements. Whether a single pass heat exchanger with a fixed tubesheet, a multi-pass design with a floating tubeplate, or u-bundle design, we can provide the most economical and reliable heat exchanger design to meet your CIP systems requirements.
