Whether to insulate and clad the exterior of evaporator vessels is determined on a case-by-case basis, depending primarily on product application and installation location. For dairy product applications, which (in most countries) are always indoors to maintain a sanitary operating environment, evaporator vessels are not insulated to avoid having a confined space (the insulation space) where microbiological growth could develop. The customer has full access to all vessel exterior surfaces for a sanitizing cleaning at any time should they choose. The evaporators for these applications are designed to account for a modest loss of thermal energy into the process room, which is generally only on the order of ~2 to 3% of the evaporator’s energy consumption as the evaporator process room is typically warm year-round. Evaporators for product applications that can be located outdoors (such as juices, non-dairy foods or chemicals) or in process buildings that can be cold in winter conditions are nearly always insulated and clad to minimize radiant thermal losses. Variable weather conditions such as wind and precipitation will disrupt steady-state evaporator operating conditions. Insulation and cladding in these applications reduces the influence of those variable operating conditions.

Hi, why don't we see evaporator vessels insulated? Surely this would reduce energy and assist the ambient temperatures for the operator, technicians?

@@calorisengineering I've worked with 4 dairy evaporators, milk, whey, whey permeate and D90. None were insulated. What's your experience?
