Blondelle overhaul spare kits, protective boots, and accessories

To preserve instrument calibration and mechanical integrity, Blondelle supplies service spare parts and protective accessories. Replacing worn seals, inspection glasses, and rubber boots prolongs gauge working life under rugged field service duties.

Replacement front sight glasses and threaded retaining bezels for 60, 80, and 100 mm gauges
Shock-absorbing rubber gauge boots protecting delicate mechanical movements from impact damage
Port sealing gasket packs, core depressors, and replacement needle packing glands for manifolds
Supply of Blondelle remote capillary thermometers for HVAC heat exchange diagnostics

Mounting and pulsation dampening of Blondelle A Lame Acier steel blade pressure gauges

Mounting Blondelle A Lame Acier pressure gauges on commercial refrigeration discharge lines requires careful attention to compressor pressure surges.

The patented steel blade mechanism possesses high inherent mechanical fatigue strength, but severe hydraulic pulsation warrants capillary coils or throttle screws. Threaded ports seal via copper or fluorocarbon crush washers without cocking flange faces.

Tightening the instrument must be performed with an open-end wrench applied strictly to the brass connector flats, never by twisting the gauge housing. In severe vibration environments, silicone oil filled variants provide smooth needle movement and long-term zero pointer retention.

Operation and seal integrity verification of Blondelle refrigeration manifold blocks

Before proceeding with evacuation or charging operations, Blondelle refrigeration manifold blocks undergo seal integrity checks. Technicians close all handwheel needle valves with controlled seating torque to avoid damaging precision fluoropolymer valve seats.

Applying dry nitrogen up to twenty-five bar verifies tightness across the sight glass seals and charging hose access ports. The smooth multi-turn action of stainless valve stems avoids pressure shocks when introducing liquid refrigerant into the system.

Upon concluding service tasks, technicians vent residual line pressure and install protective dust caps over all hose fittings.

Calibration and recertification procedure for Blondelle F-GAS PED reference gauges

Precision vacuum gauges and Blondelle F-GAS PED calibration standards serve for routine validation of field instrumentation. During laboratory calibration, technicians connect the unit to a deadweight tester or digital pressure calibrator.

Increasing test pressure in controlled increments with dwell periods across five reference points evaluates scale linearity and diaphragm hysteresis. If systematic zero shift occurs, technicians utilize the accessible zero adjustment screw on the gauge bezel to restore accuracy.

Regular recertification ensures dependable vacuum level readings during moisture dehydration of chiller circuits.

Application guidelines for Blondelle instruments in transcritical CO2 (R744) circuits

Operating with transcritical carbon dioxide in industrial refrigeration installations requires dedicated Blondelle CO2 Transcritical manifolds and ultra-high-pressure gauges.

Working pressure on the gas cooler discharge reaches up to one hundred sixty bar, far exceeding conventional fluorocarbon systems. The gauges feature heavy-duty steel ports and integrated overpressure safety release valves.

Technicians must verify pressure ratings across all manifold hoses prior to charging. Personnel must observe safety standards, avoiding rapid gas venting to eliminate dry ice formation inside valve channels.

Inspection and preventive maintenance of flexible high-pressure charging hoses

High-pressure charging hoses from Blondelle undergo regular inspection for surface abrasions, kinks, or outer sheath blistering. Gaskets inside the knurled brass nuts must be inspected prior to each connection with system service valves.

Technicians immediately replace hardened or cracked seals using factory elastomer gasket sets. Quick Coupler adapters are cleaned with pure isopropyl alcohol to remove accumulated compressor lubricants and debris before lubricating locking ball bearings with synthetic refrigeration oil.

Proper hose handling prevents refrigerant emissions during maintenance.

Model identification and cross-referencing of Blondelle replacement spare components

Accurate ordering of replacement dial dials, front lenses, manifold valves, and overhaul kits from Blondelle / Panimpex NV relies on dial markings and unit nameplates.

The dial face identifies accuracy class, pressure span in bar or PSI, supported refrigerants, and housing diameter (60, 80, or 100 mm). The manifold block carries stamped batch codes and connection thread specifications.

Providing a sharp photo of the dial and naming the system refrigerant enables swift selection of exact replacement components.
