DSC_0388-brite-longRectorSeal® Corp., Houston,  a leading manufacturer of quality HVAC/R products, introduces the Desolv Cleaning Kit, the industry’s quickest and most convenient kit for the cleaning and post clean-up of all ductless mini-split air conditioner evaporator coils and blower fan blades.

The Desolv Cleaning Kit features a patent-pending collapsible, pliable two-inch-wide plastic framework with drawstrings for tightening around any mini-split brand evaporator  encasement up to 45-inches wide. Two heavy-duty  funnel-shaped, 45 x 2-inch-wide orange plastic collection bags are designed with perforations for hooking onto the framework’s hang knobs and a pliable plastic splash guard for wall protection behind the evaporator coil. The collection bag includes an eight-foot-long extendable drain orifice tube for accommodating unconventionally high evaporator coil locations. Also included is a five-gallon pail that doubles as a storage/carrier for collecting contaminants, as well as a gallon container of Desolv evaporator coil and blower cleaner.

Previously, service techs have not applied enough cleaning agent for thorough cleaning in fear of damaging surrounding property or have jerry-rigged time-consuming and less foolproof methods, such as duct-taping plastic garbage bags around the evaporator coil to protect walls and floors. The Desolv Cleaning Kit’s hook-up and disassemble process requires less than a combined five minutes.

The kit includes the following components:

  • one gallon of patented Desolv coil cleaning agent;
  • one five gallon collection/carrying pail;
  • collapsible framework with drawstrings for tightening around the evaporator encasement;
  • a plastic splash guard to protect the wall behind the evaporator; and
  • two funnel-shaped bags for collecting the cleaning agent into the pail.

The kit is designed around RectorSeal’s odorless Desolv, the HVAC industry’s safest, non-caustic coil cleaning agent developed especially for mini-split systems in  healthcare, clean rooms, data centers and other sensitive environments. Desolv dislodges and dissolves dirt, biological contaminants, debris and films within minutes without harming the aluminum, copper and metal alloys of sensitive evaporator coil tubing, fins and the unit’s plastic housing cover.

Other features of the kit are:

  • Replacement bags are available in a 10-pack;
  • Translucent bags allow visibility of descending liquids and particulates;
  • collapsible framework has an inner side gasket material to prevent scratching of mini-split exterior finishes; and
  • Available through all major HVAC wholesale distributors.

The Desolv Cleaning Kit is a perfect complement to RectorSeal’s full line of ductless mini-split installation accessories such as NoKink–kink-free lineset connection; GasGuard and Novent®–locking caps for condenser refrigerant access valves; SlimDuct® and Fortress–lineset protection duct; ACTabsDMSS–drain pan mold prevention; PairCoil–pre-insulated linesets; Safe-T-Switch®  and AquaGuard® condensate shut-off switches; Aspen® Pumps–condensate pumps; and a variety of other accessories for condensate management and equipment mounting.

ac-locking-valveA recent story was published  in Southern California about the problems associated with huffing, in Riverside County, an inland area southeast of Los Angeles.  The accounts detailed in the story apply to any commercial business in any part of the country.  Of course, certain aspects of this story also apply to residential installations.

Please read the story and be sure to pass-along in your business and your sphere of influence:

Written by Bob Pratte, PE columnist published in PE magazine October 3, 2014

The installation of our locking refrigerant caps deters children, thieves and other unauthorized individuals from so easily committing dangerous actions, and helps to limit the liability associated with illness and injury.  Additionally, the expense of servicing and replacing a lost (or compromised) refrigerant charge, the lost revenue of having an unconditioned place of business and the frustration associated with all of this for a business owner and manager are problems which can be substantially mitigated with the installation of our locking refrigerant caps.  .

Obviously, the actual cutting of copper refrigerant tubing is something that is done fare less than the bleeding of the access valves and in certain installations, a contractor might need to suggest further protection to be considered by a building owner or facilities manager trying to reduce access to the refrigerant.


This story continues to establish the real and immediate need for our locking refrigerant caps – – not just on new installations (which is required by code), but also on all existing condensing units which are exposed to unauthorized access.  We have the solution to the most commonly abused method of huffing (the simple depressing of the stem of the access valves): share it with others.  Novent® and GasGuard™ Locking Refrigerant Caps.
