All Design Proposal: Hygiene/Mould

A practical library of design proposal letters, sample specifications, and editable spreadsheets for HVAC&R consulting engineers and D&C contractors.  These templates help you turn technical data and product information into clear, professional design summaries — suitable for client proposals, alternate submissions to builders, and design development. Naturally we have focused our efforts on more innovative products rather than recreating what you already have from the last job. You can adapt each template freely — they’re meant as a head start, not a locked-down spec.

Design Proposal: SAN-AIR Vapour-Phase IAQ Treatment For HVAC Refurbishment & Existing HVAC

Dear Project Team, As part of the mechanical refurbishment works, I am proposing the integration of SAN-AIR vapour-phase antimicrobial products within the existing HVAC systems (AHUs, FCUs, split systems and cassette units). This solution directly addresses the mould, bacterial growth and IAQ issues we commonly observe in ageing systems — particularly where coils, return-air paths, ceiling plenums and condensate trays Read more…

UVC Treatment Behind Evaporator Coils – Freezer Room and Cold room -Design Proposal Template

Dear Project Team, Following our recent inspection of the existing cold and freezer rooms, visible mould growth and biofilm formation were observed on and around the evaporator coil assemblies, including coil fins, drain trays, and room surfaces.   While room air temperatures are low, the evaporator environment itself operates with persistent moisture, intermittent warming during defrost cycles, and organic loading, Read more…
