GO Distribution offer Super Seal sealant to find sneaky leaks in HVAC/R system.
Many commercial and industrial processes are heavily dependent on efficient heating, ventilation, air conditioning and refrigeration (HVAC/R) systems.
Energy-sapping leaks of refrigerant from chilling systems, processing lines and perishable product handling facilities can drive their owners to distraction by costing heaps of money to find and fix – not to mention the costs incurred as government moves to curb carbon emissions push up energy bills and the government cracks down on building and atmospheric polluters.
The problems are often sneaky leaks - tiny holes sometimes only microns across – in the evaporators, condensers and pipelines found in the HVAC/R systems that are so vital to every modern commercial and industrial plant’s comfort and function, says HVAC and refrigeration specialist Gary Oborne.
“When things go wrong with HVAC/R systems, factories and shops face expensive spoilage of refrigerated goods and processes, workers face discomfort and industrial processes face disruption – it’s a major headache.”

“Left unchecked these pinprick holes can leak refrigerant, push up energy bills and pollute the environment. The trouble is that these micro leaks are hard enough to find when the refrigerant pipelines are accessible - and near impossible when pipelines are buried in a building’s structure, under cement, or in walls and ceilings.”
“You’d have to tear up the building to get at them. Sometimes the detection job is just too hard and building managers end up having to throw out perfectly good systems in frustration after having service techs in multiple times.”
The Super Seal sealant, available from GO Distribution, is formulated to permanently repair leaks up to 300 microns in evaporators, condensers and pipelines.
The leak repairing process can be compared with how blood clots to stop the bleeding of a wound in a human body. The Super Seal is injected to circulate with the refrigerant and oil that is the lifeblood of an HVAC/R system.
At the point where the refrigerant leaks through the tiny punctures in the system, it begins to lower the ambient air temperature down to the dew point, when micro droplets of moisture are deposited around the leak area.
The escaping refrigerant containing Super Seal reacts with this moisture to form a permanent low tensile crystalline structure, which seals the hole from the inside out.
The sealant has already proved to be a benefit for a heating, ventilation, air-conditioning and refrigeration (HVAC/R) specialist operating in Australia’s tropical north.
Rob Middleton, a Cairns based technician, used Super Seal in two recent applications that involved a refrigerator and an air conditioning unit that were both in good working order apart from small but worrying persistent leaks.
The refrigerator unit was in premises where food was handled and the HVAC unit was in a commercial building area.
“On both projects, the customer was concerned that they would have to fork out thousands of dollars for new equipment, but when we discovered Super Seal it was the logical resolution,” said Rob Middleton.
“We found electrolysis occurring on the failing air conditioning condenser and to replace that alone was going to cost $4500. But using gas, a dryer and Super Seal it cost less than $1000.”
“It was the practical solution and we haven’t had a problem since, it’s a 100 per cent success and I have no reason to doubt the sealant will continue to be effective in repairing any future leaks that may occur without us even knowing.”
Similarly inexpensive and effective results were achieved on the refrigerator, said Rob Middleton, who now carries sealant from the range of Super Seal as an option for customers who have micro leaks in systems that cannot be found or accessed easily.
Rob Middleton’s experience adds to a global list of success stories where Super Seal has saved customers time and money says Gary Oborne.
One case involved a leaking chiller that forced the HVAC/R engineer of a car manufacturing plant to decide between a costly production shutdown and using Super Seal to eliminate the leak, which it did.
Shutting down the chiller system, which cooled 39,366L of honing oil used in the engine block cutting process, would have run up costs in service and parts and disrupted production.
“We also had a case involving refrigerant lines running nearly 30 metres under a concrete deck located at a major supermarket franchise store. They totally replaced sub-surface components but even that didn’t work satisfactorily.”
“The problem persisted until the service technician put two 85 gram (3-ounce) cans of Super Seal into the supermarket system – and breathed a sigh of relief when, soon after injection, the system retained optimum pressures,” said Gary Oborne.
“On subsequent routine maintenance visits, this highly experienced technician continued to be amazed at the perfect pressures the system exhibited.”
“He has since used the sealant on a supermarket walk-in cooler, a restaurant ice machine with an “irreparable” evaporator plate, and several residential HVAC central air conditioning systems.”
The Super Seal sealant is suitable for all air conditioning and refrigeration applications and is compatible with all oils and refrigerants.
The Super Seal will not interfere with compressor valves, capillary tubes or TX valves and will remain stable within the refrigerant stream.
The Super Seal sealant is available in three varieties, for systems from: Super Seal ACR 0.7kW → 5.3kW (1/10hp → 7hp); Super Seal HVACR 5.3kW → 17.6kW (7hp → 23hp) and Super Seal Commercial 17.6kW → (23hp →). The Super Seal Pro is suitable for automotive and mobile air conditioning applications.
