HVAC Cleaning Chemicals

We offer HVAC Cleaning Chemicals. These Cleaning chemicals for hvac industry play a vital role in keeping industrialImage heating and cooling equipments operating efficiently. Of particular importance is the removal of foulants such as machine oils, grease, metal oxides, metal working fluids, dust-dirt and inorganic foulants. Cleaning of new closed loop chiller water or brine systems is just as important as cleaning old ones.


Closed Loop Chiller Water System Maintenance is a very vital part of hvac and acnr maintenance program. Heavy losses can be incurred due to minute negligence in the closed loop system maintenance, in terms of power loss, system efficiency loss, htf (heat transfer fluid) and refrigerant fouling and degradation, loss of system life, unscheduled maintenance and cleaning jobs for descaling and fixing leaks and bursts due to corrosion. The major area of closed circuit maintenance are: proper system cleaning, derusting & passivation after commissioning and controlling corrosion. Since, fouling of heat transfer fluids or water can cause heavy corrosion of system metal and degradation of htf properties. Fouled system result in drastically reduced heat transfer efficiency and cooling capacity of the system. Chemtex speciality ltd offers a wide range of cleaning chemicals for hvac industry:-

Closed Loop Chiller Water Non-Oxidizing Microbiocide

A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required.


Cooling towers are heat removal devices used to transfer process waste heat to the atmosphere. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near the dry-bulb air temperature.


Biocides and MicroBiocides are chemicals that prevent and eradicate unwanted biological fouling from the system. Biocides are of various nature such as oxidizing, non-oxidizing, cationic, anionic etc. Biological Fouling or Biofouling is the undesirable accumulation of micro-organisms, algae and diatoms, plants, and animals on surface, pipelines and heat-exchangers of cooling systems. Bio-fouling can be of aerobic (that require oxygen) or anerobic (that don’t require oxygen) organisms. In general the former is found in Cooling Towers and the later in closed circuit systems.


Another very important reason for using Cooling Tower Micro Biocides in cooling towers is to prevent the growth of Legionella, including species that cause legionellosis or Legionnaires’ disease, most notably L. pneumophila, or Mycobacterium avium. The various Legionella species are the cause of Legionnaires’ disease in humans and transmission is via exposure to aerosols—the inhalation of mist droplets containing the bacteria. Common sources of Legionella include cooling towers used in open recirculating evaporative cooling water systems, domestic hot water systems, fountains, and similar disseminators that tap into a public water supply.


Micro biocides function in eradication of sulfate reducing bacteria, aerobic and anaerobic bacteria that are formed and found in Cooling Tower Water.Micro Biocides are very vital for Closed and Open Circuit Cooling Water Treatment.


TCF (Totally Chlorine Free) micro biocides are compatible with heat transfer fluids (HTF) and can be used without any fear of corrosion of chlorine addition to the system or depletion or degradation of HTF and corrosion of PHE (plate type heat exchangers)


Chemtex’ s Closed loop Micro biocide surpasses the performance of other such less effective closed loop treatment chemicals (such as Nalco 7330, Nalco 77352NA etc.)



Engine Jacket, Chiller Water Circuit, Glycol Brine System, Hot Water Circuit, Engine Coolant, Process chilling and heating etc.



Chemical Type:Organic/Inorganic Chemical Compound (TCF)


Specific Gravity :Ranges from 1.0-1.2 depending upon product

The amount of Closed Loop Biocide required to inhibit or remove bio fouling depends on the type of system, application, re-circulating fluid property and plant operating conditions. The specific dosage rates will be specified by the CSL technical representative.


Major Benefits:

    1. Prevention of Bio-fouling of system
    2. Avoid plugging of nozzles
    3. Avoids MIC (Microbiologically Induced Corrosion)
    4. Prevent Water Borne Diseases
    5. Improve heat loss because living organisms cause rise in temperature of water

Inhibited Sulfamic Acid Boiler Descalant

Chemtex Speciality Limited is engaged in formulation and supply of a entire range of Boiler Water Treatment Chemicals. These chemicals are used for removing and preventing mineral scale deposition and rusting of the water / steam side of boiler internals.


Chemtex contribute to the overall safety of operation of the boiler or water.  And assist in the maintenance of high heat-transfer efficiency in boiler or water heater by:-

  • Preventing deposition of precipitated scale or other debris
  • Preventing corrosion or deterioration of surfaces in contact with water


Boiler Feed water treatment chemicals removes dissolved oxygen and reduce corrosion in the feed water circuit and thus protects the equipment against damage and reducing the potential for unscheduled downtime. These chemical treatments also reduce the amount of metal oxides and metal hydroxides (rust) entering the boiler to maintain clean boiler tubes and improves fuel efficiency.


Boiler internal treatment chemicals maintains clean boiler tubes surfaces and minimize metal cavitation (corrosion) – reducing the chance of overheating or failure. Control of corrosion and scale deposition helps to increase plant reliability and availability. It protects equipment, and reduces over all maintenance and fuel costs. In addition, some treatment chemicals can reduce the tendency for boiler water to carry over to the steam, thus, protects superheaters and steam turbines from damages.


Descalants or Descaling Agents are chemical compounds that effectively dissolves, disperse or purge the scales, rust and soil deposits from heat exchangers and pipelines by means of re-circulation method, fill and soak method or immersion method. A descalant is always designed by keeping in mind the type of deposit and metallurgy of the system. Proper Corrosion Inhibitors are added in descalants to avoid damage to system metals.


After acidic descaling of system, it is important to passivate and neutralize the system with proper Passivating Agents for avoiding chances of flash rusting after descaling. In some cases Scale Softeners and mechanical means like brushing and scrubbing of tubes is also required for heavily fouled systems.

Descaling is a labor oriented job and requires system downtime. Hence, the use of alternatives such as Online Descalants and Antiscalants are getting popular. Chemtex offers a wide range of descalants under its registered trade names for various types of small, medium and large size boilers.
