Hospitals ventilate harder than almost any other building type, and operating theatres and isolation wards sit at the extreme end: 20+ air changes per hour of conditioned air, strict directional pressure relationships, and zero tolerance for contaminated air reaching patients or staff. That intensity makes recovery valuable but also constrains it. This article covers where the load sits, why infection-control rules usually push you to plates rather than wheels, where a wheel is still acceptable, and what payback looks like in practice.<\/p>\n

Theatres demand 20 to 25 air changes per hour of conditioned, largely outdoor air, and isolation rooms need inward directional pressure with high outdoor-air fractions. Heating, cooling, humidifying and moving that air dominates the surgical-suite energy cost.<\/p>\n
Infection control requires that supply never receive moisture, particles or pathogens from exhaust. A plate keeps the streams on opposite sides of a solid surface with no mixing path, so sensible-only recovery is inherently safe.<\/p>\n
A wheel may be acceptable on non-critical exhaust where purge sectors and certified low leakage meet the infection-control risk assessment, but critical isolation and theatre supply normally stay with plates.<\/p>\n
Because the ventilation rate is high and continuous, a properly specified plate core recovers a large, steady energy fraction, and the payback is usually strong despite the conservative, contamination-safe technology choice.<\/p>\n
