Customer focused services
K. Guller, LLC insulates mechanical plant equipment — boilers, chillers, storage and process tanks, heat exchangers, pumps, air handlers, and breeching — using board, blanket, and block systems finished with metal or PVC jacketing. Components that need maintenance access get removable blankets instead of hard insulation, so service work doesn’t destroy the system. Union crews serve central plants and mechanical rooms across Pennsylvania, New Jersey, Delaware, and the surrounding areas.
Casings, breeching, economizers, blowdown and flash tanks
Barrels, waterboxes, and suction piping, vapor-sealed against condensation
Hot water storage, condensate receivers, process and buffer tanks
Shells insulated hard; heads and channel covers fitted with removable blankets for tube-pull access
Hot and chilled service, with removable covers where seals need service
Board and liner systems on casings and built-up units
The recurring design decision: what gets hard insulation and what gets a removable blanket. Anything opened for maintenance — heads, manways, handholes, waterboxes, pump casings — should get a removable blanket; everything else gets a permanent finished system.
Yes — cold equipment is a bigger condensation risk than cold pipe, because large flat and curved surfaces are hard to vapor-seal and sit below dew point year-round. An uninsulated or badly insulated chiller barrel sweats onto the housekeeping pad, corrodes, and raises humidity in the plant. We insulate cold equipment with closed-cell or vapor-jacketed systems, sealed continuously, with removable vapor-tight covers over service points.
Mechanical rooms are seen by owners, inspectors, and every trade on the job — the finish is the reputation. Options by exposure:
All finishes are detailed to shed water and survive the plant’s traffic — kick plates and protection at walkways where equipment gets climbed.
Find answers to common questions about our services, processes, and how we work with clients across various industries.
Yes — boiler casings, breeching, and connected vessels are among the highest-loss surfaces in a plant. Modern packaged boilers arrive insulated, but field-erected units, breeching, tanks, and repaired sections routinely need field insulation.
Yes — with removable blankets rather than hard insulation, so the heads can be pulled for tube service and the covers reinstalled in minutes.
Usually. Most equipment insulation and re-insulation is performed on live plants with normal hot-work and access precautions; we phase around operations and outages.
Bare hot surfaces — tanks, breeching, exchanger shells, and stripped components. An insulation energy appraisal ranks every surface by dollar loss so the highest-payback items are done first.
