Sanitary heat exchangers are often required in the food and pharmaceutical industries. Constructed similarly to typical heat exchangers, sanitary exchangers can have special design requirements such as;
- Seal welded of joints
- Polished surfaces
- Sanitary tri-clamp fittings
- Teflon©, Gylon Fawn, Viton© or other special gasket materials
- Manufactured to 3a Standards and Stamped
- Clean in place design
Sanitary construction Plate Heat Exchangers
API Heat Transfer’s line of Schmidt stainless steel Plate Heat Exchangers combine compactness, high thermal efficiency, low volumetric product hold-up inside the unit, and ease of inspection with the requirements for sanitary installations. Corrugated plates are available in 316 stainless steel, or exotic materials as required for long life. API’s SIGMA Plate & Frame Heat Exchangers come in a wide variety of plate configurations and frame designs to suit processors applications and budget. Various thermal plates are available for particulate-free low viscosity homogeneous fluids, medium viscosity liquids with fine suspended solids, high viscosity liquid foods, and those with higher concentrations of large suspended fibers.
Proper thermal treatment of liquid food products is essential to human safety; acceptable shelf-life; maintaining attractive taste, natural colour and fresh aroma; and even cost effective transportation.
With our Schmidt brand of Plate Heat Exchangers and complete Thermal Process Systems, API Heat Transfer has over a century of experience providing innovative solutions to the; Pharmaceutical , Liquid Food, Beverage, Brewery and Dairy industries.

Point-Of-Use (POU) Sampling System
Exergy Point-Of-Use systems dispense instant, temperature controlled WFI or PW, and are designed to meet the high quality requirements and hygienic standards of the pharmaceutical industry. When not in use, a continuous flow of hot water (from the main loop) maintains sanitization. Exergy offers standard models using our compact, high performance heat exchangers for the most demanding conditions. Many features and options can be customized.
Benefits:
- Instant cold or hot WFI or PW availability at POU
- Continuous flow of hot water keeps it sanitized at all times
- Automated or manual operation
- PLC with touch screen HMI with many operating modes
- Fully drainable on product side, with no dead legs
- Easy to install, operate and maintain
- CIP and SIP capable
Design Features:
- Enclosed locking cabinet
- Sanitary double tube sheet heat exchanger eliminates risk of cross contamination between product and working fluid
- All product contact surfaces are passivated, less than 20 Ra and electropolish available
- 316L stainless steel construction
- Full quality documentation provided
- ASME BPE Compliant
Typical Applications:
- Cool WFI/PW from 80-85°C to 20-40°C
- Water For Injection (WFI) systems
- Purified Water (PW) systems
