Novozymes - ONLY had good experiences
Cooling pumps in Novozymes Biotechnology Tianjin.
Highly Efficient and Reliable DESMI Pumps for Pharmaceutical Company
- DESMI Pumps used as cooling pumps in Novozymes Biotechnology Tianjin.
Novozymes has invested in additional enzyme granulation capacity at its Chinese Tianjin plant. As one of Novozymes’ three strategic production bases around the world, the plant is capable of manufacturing various enzymes used in industries, such as biofuel, food, beverage, and detergent. The extended granulation capacity allows Novozymes to produce more granulated enzymes, mainly for the detergent and food industries. Novozymes offers sustainable solutions to increase yields and to replace, reduce, or optimize the use of petrochemicals, thereby contributing to energy savings and emissions reduction.
DESMI is proud to be the preferred supplier for Novozymes Tianjin plant with a supply of 12 pumps for their expansion project in 2009 and another 12 pumps to Novozymes back in 1998 through the EPC ABB Engineering Ltd. All pumps have now been in operation for many years without the need for any new spare parts.
Three DSL400-495A/a, four DSL300-320A/a, two NSL250-265A/a, two NSL250-415A/a and two NSL200-265/A16 pumps for cooling tower applications were supplied to Novozymes. The capacities range from 250 m3/h to 3000 m3/h, and pressures ranging from 15 to 38 mLC. Seven DSL double-suction vertical in-line centrifugal pump units are used as cooling water circulation pumps, whereas five NSL vertical in-line pump units are used as chilled water primary and secondary pumps.
Based on our experience, DESMI had a clear understanding of cooling tower pump operations and the principle of operating two or more pumps in parallel. The varying temperature between seasons and between day and night time operations requires?the capacity for cooling and chilled water pumps to vary with the fluctuation of temperature based on the following formula:
Q x (Tout – Tin) x Factor = P = Q x (Tin – Tout) x Factor.
