Product Overview
Are you struggling to control soaring summer temperatures in your commercial high tunnel, warehouse, or indoor facility? Our professional-grade Greenhouse Evaporative Cooling Pads (Coated 1 Side) are the ultimate high-efficiency climate media designed to stabilize indoor environments. Greenhouses naturally trap intense solar heat, stressing crops and reducing worker productivity. This premium evaporative swamp cooler media passes hot ambient air through a consistently wet matrix, instantly lowering temperatures to create a perfectly balanced microclimate for vigorous plant growth.
Built for a long-lasting and low-maintenance operational lifespan, our structural pads are constructed from dense, high-absorption cellulose virgin Kraft paper (110 grams per square meter) infused with premium rigidifying agents and wetting additives. To solve the industry-wide problem of premature scaling and calcium clogging, the air-inlet side of these pads is dipped in a specialized heavy-duty black plastic resin. This protective coating acts as a shield against harsh mineral crusts and aggressive abrasion, significantly extending the life of your cooling system.
Key Features
- Black Resin Anti-Scaling Protection: Features a specialized single-side black plastic resin dip that dramatically minimizes calcium scaling, mineral buildup, and physical wear.
- Premium 110 GSM Kraft Paper: Constructed with heavier cellulose virgin Kraft paper and high resin content for ultimate structural memory and water absorption.
- Multi-System Compatibility: The standard 12-inch-wide tracking profile is stocked in multiple lengths and thicknesses to fit leading commercial evaporative frameworks seamlessly.
- Self-Cleaning & Self-Supporting: Structural cross-flute geometry delivers an advanced low-pressure drop design that is completely self-supporting and naturally sheds debris.
- Proven 18-Month Warranty: Backed by a trusted 18-month limited manufacturer warranty; commercial volume discount pricing is available for industrial clients.

Professional Operation & Maintenance Guidelines
Due to natural underlying mineral saturation, it is highly recommended to replace your cooling pads every 3 to 5 years. To maximize efficiency and ensure the longest operational life, follow these core maintenance steps:
- Control pH Levels: Maintain your distribution water pH strictly between 6.0 and 8.0.
- Algae Prevention: Cycle off your water pump daily and allow the pads to dry completely for a full, continuous 24-hour block to starve out algae spores.
- Bleed-Off Rate: Maintain a continuous 3% to 5% system water bleed-off rate to discharge concentrated minerals before they calcify.
- Sun Shading: Shield both your cooling pads and water sump reservoir from direct, intense sunlight exposure to reduce algae growth.
- Flush and Disinfect: Use a soft-bristled brush to gently sweep away loose surface debris, then drain and completely disinfect the entire water distribution lines quarterly.
- Water Management: Ensure a steady, uniform flow across the headers, and never allow the bottom edge of the paper pads to permanently sit submerged in stagnant water.
Crucial Motor Freight Shipping Requirements
Please note that large size variations (such as our 6″ x 12″ x 60″ / 5-pad or 1-pad bundle kits) exceed standard parcel weights and **must ship via a Motor Freight Carrier**. Freight deliveries are bound by strict freight regulations:
- The destination must be a physical commercial business or residence capable of accommodating semi-truck tractor-trailers up to 70 feet in length (PO Boxes are invalid).
- An adult must be present at the delivery location to receive, sign for, and manually unload the heavy shipment from the back of the cargo truck.
- Optional services such as carrier lift gates, limited access destinations, or inside delivery requests may incur additional carrier freight surcharges.
Frequently Asked Questions (FAQ)
Q1: What is the benefit of having the evaporative pad coated on one side?
A: The single-sided black plastic resin coating is applied specifically to the air-inlet side of the pad. This face takes the brunt of incoming wind, dry dust, and direct water evaporation where mineral deposits form fastest. The slick resin coating makes it difficult for minerals like calcium to stick, letting the water wash scale away while preventing structural sagging.
Q2: How often do I need to replace my greenhouse swamp cooler pads?
A: Under standard commercial operation and with proper seasonal maintenance (such as managed dry-outs and quarterly system flushes), these premium 110 GSM pads provide a reliable service life of 3 to 5 years before mineral saturation requires a total core replacement.
Q3: Why can’t I cycle the water pump on and off throughout the day to save water?
A: Constantly cycling your pump on and off causes the cellulose paper to repeatedly undergo intense wet-and-dry stress transitions. This structural friction rapidly breaks down the virgin Kraft paper fibers and accelerates mineral crystallization on the flute walls, drastically shortening the pad’s working life.
Q4: Do these cooling media sheets fit other brands of evaporative systems?
A: Yes! Our 12-inch-wide tracking media sheets are crafted to universal dimensional profiles. As long as you select the corresponding thickness, length, and flute angle, these pads will fit perfectly into systems from most major greenhouse climate control manufacturers.
