Before you specify

Food-industry use does not imply direct food-contact approval. The catalogue heat-capacity unit needs clarification and is not reproduced here. Confirm application-specific documentation.

FROM FORMULATION TO APPLICATION

Built around indirect refrigeration.

LM-4B is described for secondary cooling in cold storage, chemical processing and pharmaceutical systems. Its modified ternary-alcohol formulation includes corrosion-control and stabilising additives.

01 / APPLICATION NOTE

Separate the fluid from the product

In an indirect system, the coolant carries cooling capacity through a separate circuit. Suitability for food-processing equipment does not establish direct food-contact approval.

02 / APPLICATION NOTE

Specify the supplied formulation

The original product information notes that colour can be customised. Appearance alone is not a reliable way to identify a formulation or concentration.
