Product Overview
BSTFLEX removable heat exchanger insulation jackets are custom-fabricated fitted thermal covers for approved hot surfaces on plate-and-frame, shell-and-tube and industrial process heat exchangers. Modular reusable sections can be designed around exchanger bodies, heads, ports, nozzles, supports and service areas, allowing inspection or cleaning without destroying the complete insulation system.

Heat Exchanger Types

• Plate-and-frame heat exchangers
• Gasketed plate heat exchangers
• Brazed plate heat exchangers
• Shell-and-tube heat exchangers
• Heat exchanger shells and bodies
• Channel heads and removable end covers
• Heat recovery equipment
• Industrial oil coolers and process exchangers
• Boiler and condensate heat-transfer equipment
• Custom skid-mounted exchanger assemblies

Plate Heat Exchanger Insulation Jacket
A plate-and-frame heat exchanger jacket is manufactured to fit the frame, movable pressure plate, plate pack and connection ports without preventing access to identification plates, drains, ports or tightening components that require inspection. Covers can be produced as front, rear, side and top sections with shaped openings around pipe connections; multi-piece layouts permit removal of selected panels for inspection or cleaning. Section labels assist correct reassembly.

Shell-and-Tube Heat Exchanger Insulation Blanket
Shell-and-tube jackets may include separate insulation for the cylindrical shell, channel head, bonnet, removable cover, nozzles and saddles. Separating shell sections from heads allows access to tube bundles or end covers without removing insulation from the entire exchanger body. Nozzle covers and flange jackets may be manufactured as individual parts for separate maintenance.

Modular Jacket Design
Large exchangers are easier to handle when insulation is divided into practical sections. Design features include:

• Numbered body panels
• Separate head and channel-cover jackets
• Individual nozzle and flange covers
• Inspection and nameplate flaps
• Openings around supports, legs and saddles
• Removable panels around drains and vents
• Overlap flaps between adjoining sections
• Installation-direction and equipment labels

Material Construction
Jacket Component | Typical Options | Design Considerations
Outer protective cover | Silicone coated fiberglass, PTFE coated fiberglass, aluminized fiberglass or other coated heat-resistant fabrics | Indoor or outdoor location, oil, moisture, abrasion, radiant heat and cleaning
Insulation core | Fiberglass needle mat, silica needle mat, ceramic fiber insulation or aerogel-based insulation | Operating temperature, thermal target, available space, section weight and thickness
Hot-face liner | Fiberglass fabric, silica fabric, stainless steel foil or stainless steel mesh | Contact temperature, surface condition, vibration and repeated handling
Closure system | D-rings and straps, stainless steel hooks, springs, lacing wire, buckles or other removable fasteners | Temperature, panel size, installation clearance and removal frequency
Reinforcement | Quilting pins, reinforced seams, stainless steel mesh, support tabs and local wear layers | Vertical position, large panels, curved heads and insulation movement

Note: The temperature rating of a single material is not the rating of the finished jacket. The full assembly rating depends on liner, insulation core, outer cover, thread, fasteners and installation method, chosen according to actual operating and exposure temperatures.

Hot-Service and Cold-Service Designs
Hot-service jackets reduce heat transfer while preserving maintenance access; insulation thickness and materials depend on exchanger temperature, ambient conditions, required external surface temperature and available clearance. Cold-service designs require control of condensation and water-vapor entry; standard hot-service stitched blankets do not automatically provide a continuous vapor barrier and require review of seams, penetrations, closures, drainage and vapor sealing for sub-ambient applications.

Information Required for a Plate Heat Exchanger

• Equipment manufacturer and model if available
• Overall frame height, width and depth
• Plate-pack dimensions
• Location and diameter of every connection port
• Position of tightening bolts and frame supports
• Location of drains, vents, gauges and nameplates
• Dimensions and position of mounting feet
• Required panels or areas that must remain removable
• Operating temperatures on both fluid sides
• Available installation and removal clearance

Information Required for a Shell-and-Tube Exchanger

• Shell outside diameter and insulated length
• Head or bonnet type and overall dimensions
• Channel-cover diameter and bolt projection
• Nozzle outside diameters, orientations and flange sizes
• Position of saddles, legs, lifting points and supports
• Location of vents, drains, instruments and inspection openings
• Tube-bundle or end-cover removal direction
• Adjacent pipe-insulation outside diameters
• Operating temperature and external environment
• Preferred panel size, identification and removal sequence

Maintenance Access
Insulation layout should follow the equipment maintenance plan. Nameplates, pressure markings, gauges, drains and vents may require permanent openings or access flaps. The customer should identify every point that must remain visible or operable while insulation is installed.

Installation

• Confirm each panel number against the equipment and installation drawing
• Follow site procedures for working around the heat exchanger
• Inspect equipment for active leakage before installing insulation
• Install the lower or reference panel first when specified
• Align openings around ports, supports, drains and instruments
• Connect adjoining panels without twisting or compressing the insulation core
• Tighten closures gradually and distribute tension evenly
• Verify access to nameplates, service points and required controls

Inspection and Reinstallation
Place removed panels on a clean, dry surface and retain installation sequence. Inspect outer cover, liner, seams, fasteners and insulation core before reinstallation. Wet, contaminated or heavily compressed insulation should be evaluated rather than returned directly to service. Check heat exchanger surfaces, connections and gasket areas for leakage; a removable jacket must not be used to conceal an active leak.

Outdoor Heat Exchanger Covers
Design must address rain, wind, UV exposure, standing water and seam orientation. Suitable outer fabrics, protected overlaps and drainage-aware panel layouts are specified to prevent water entry into panel joints or service openings. Weather resistance depends on the entire jacket construction including needle holes, seams, fasteners and equipment penetrations.

OEM, Retrofit and Replacement Projects
Covers can be manufactured from drawings, field dimensions, digital measurements, templates or approved samples. Project options include part numbers, equipment tags, panel labels, installation drawings and special packaging. When replacing an existing jacket, identify previous fit or access problems so the new pattern corrects them rather than reproducing them.
