Cooling Tower Specialty

DSL 701 - Antiscalant Cum Corrosion Inhibitor

Advanced dual-action polymeric formulation engineered to keep open recirculating cooling systems scale-free while forming an electrochemical passive barrier over heat exchange surfaces.

Key Operational Benefits:

Controls Scale: Inhibits calcium carbonate, calcium sulphate & silica precipitation.

Protects Metallurgy: Prevents pitting on copper, carbon steel, and stainless steel tubes.

Maintains Clean Heat Transfer: Avoids compressor high head pressure trips.

Extends Equipment Life: Condenser tube lifespan increased from 3-7 years to 10-15+ years.

Dosing Method: Continuous or slug dosing via automated metering pump into cooling tower basin or sump based on cycles of concentration (COC).

Alkalinity Management

DSL 702 - Dealkalizer Chemical

Engineered formulation that regulates high bicarbonate and carbonate alkalinity in circulating water, preventing catastrophic scale drop-out when cycles of concentration rise.

Key Operational Benefits:

Controls High Alkalinity: Balances circulating water buffer capacity.

Reduces Scaling Tendency: Controls Langelier Saturation Index (LSI) in positive safe zones.

Water Chemistry Balance: Allows higher water cycles, saving precious makeup water.

Safe & Stable: Formulated for easy handling and continuous plant operation.

Microbiological Control

DSL 703 - Oxidizing Biocide Chemical

High-potency oxidizing agent providing rapid disinfection and destruction of planktonic bacteria, green algae, and fungal organisms in wet cooling decks.

Key Operational Benefits:

Rapid Microbe Destruction: Controls Legionella, Pseudomonas, and algae blooms.

Prevents Slime Formation: Eliminates insulating biological slime on condenser bundles.

Maintains Clean Fill Surfaces: Prevents nozzle blockage and uneven air-water contact.

System Hygiene: Eliminates odors and maintains pristine tower basins.

Persistent Biofilm Eliminator

DSL 704 - Non-Oxidizing Biocide Chemical

Broad-spectrum biocide that penetrates sessile bacterial colonies and deep extracellular polysaccharide slime layers, preventing microbiological immunity when alternated with DSL 703.

Key Operational Benefits:

Alternative Kill Mechanism: Disrupts microbial cytoplasmic membranes.

No Bacterial Resistance: Ensures consistent kill rates year-round.

Effective in Heavy Load: Works stably even in high organic matter industrial water.

Non-Corrosive to Metal: Gentle on structural components and piping.

Boiler Scale Defense

DSL 801 - Boiler Antiscalant Cum Corrosion Inhibitor

High-thermal stability polymer formulation designed to condition hardness minerals in high-temperature boiler water into a non-adherent, mobile sludge that is effortlessly purged via bottom blowdown.

Key Operational Benefits:

Stops Scale on Tubes: Prevents heat transfer drop, hot spots, and tube rupture.

Protects Metal from Under-Deposit Attack: Neutralizes corrosive cell formation.

Cuts Fuel Consumption: Clean tubes ensure rated steam generation with less fuel.

Prolongs Boiler Life: Tube life increases from 3-5 years to 10-15+ years.

Alkaline Passivation

DSL 802 - pH Control Chemical

Buffering alkaline compound that maintains the boiler water pH in the ideal protective range (10.5 – 11.5), preventing both low pH acidic thinning and localized caustic gouging.

Key Operational Benefits:

Optimum Boiler pH: Maintains stable alkaline environment.

Prevents Embrittlement: Prevents stress corrosion cracking in riveted/welded drums.

Minimizes General Corrosion: Protects drum surfaces, risers, and downcomers.

Safe & Stable Operation: Ensures smooth steam disengagement with zero carryover.

Pitting Prevention

DSL 803 - Oxygen Scavenger Chemical

Rapid-reacting chemical de-oxygenator that scavenges dissolved oxygen from boiler feed water down to zero ppb, completely eliminating dangerous localized oxygen pitting.

Key Operational Benefits:

Rapid Oxygen Removal: Scavenges O₂ before entering economizer tubes.

Stops Oxygen Pitting: Prevents catastrophic pin-hole tube punctures.

Protects Auxiliaries: Safeguards economizers, headers, and preheaters.

Clean High-Quality Steam: Safe for process heating and sensitive equipment.

Membrane Technology

DSL 501 - Advanced RO Antiscalant Chemical

Superior threshold inhibitor engineered for industrial & commercial RO systems. Prevents mineral supersaturation across reverse osmosis membranes, enabling high permeate flow and minimum reject water.

Key Operational Benefits:

Blocks 6 Major Foulants: CaCO₃, CaSO₄, Reactive Silica, Iron & Manganese, Organic matter.

Higher Recovery (60% - 75%): Delivers significantly more permeate with less reject waste.

Cuts CIP Cleaning Frequency: Extends cleaning interval from 2-3 months to 6-12 months!

Extended Membrane Life: Protects Polyamide/TFC membranes up to 5 to 8+ years.

Compatibility: 100% compatible with major membrane brands (Hydranautics, DuPont FilmTec, Toray, Suez). High TDS and silica-prone groundwater tolerant.

Closed Loop HVAC Protection

DSL 901 - Nitrite Based Corrosion Inhibitor Chiller Chemical

Advanced closed-circuit inhibitor forming an impermeable gamma iron oxide passivation barrier on steel and copper alloys in secondary chilled water loops operating between 5°C and 15°C.

Key Operational Benefits:

Multi-Metal Protection: Carbon Steel, Stainless Steel, Copper, Brass and Cast Iron.

Stops Sludge & Black Water: Keeps buffer tanks and pump seals clear of abrasive iron particles.

Lower Power Draw: Clean evaporator surfaces maintain minimum approach temperatures.

20+ Years Piping Life: Protects AHUs, fan coil units, and structural loop piping.
