QUALITY MAKES A DIFFERENCE

The HardLine Advantage starts with quality base materials and consistent manufacturing practices. EPVS ensures superior quality, performance and reliability by only using the best, most environmentally responsible raw materials.

RIGIFLEX-FR™Our proprietary RigiFLEX-FR™ semi-rigid polymer base material is industry-leading. RigiFLEX-FR™ is designed and purpose-built for mine and tunnel ventilation. No laminated layers to fracture, crack, tear or lose bond when subjected to shock and abrasion.RigiFLEX-FR™ is durable, resilient, resistant to puncture and deformation.

MANUFACTURINGHardLine Ducting is manufactured with precision and assembled using fusion-welding technology for high-strength. Our process ensures sizes remain accurate and reliable from specification to installation. EPVS annually audits and certifies its processes using the ISO 9001 program.

FREIGHT, LOGISTICS & INSTALLATIONFREIGHT & LOGISTICS:HardLine is compressed for shipping and storage, making it cheaper to ship than steel and fiberglass ducting.

INSTALLATION:HardLine couplings require no additional tools. The coupling installation process is simple to understand and requires low physical exertion. The coupling is shared across all HardLine products, accessories and pressure configurations. The system is efficient because it’s simple, fast and repeatable.

The HardLine 3-Step Coupling: STEP 1 – ‘NEST-to-fit’, STEP 2 – ‘ZIP-to-lock’, STEP 3 – ‘RATCHET-to-seal’ DONE!

PERFORMANCELOW AIRFLOW RESISTANCEHardLine Performance Ducting offers a low coefficient of friction and efficient coupling system that results in significant air performance advantages over steel, fiberglass and flexible ventilation products. The comparative chart below outlines the efficiency gain of HardLine Ducting.

HIGH EFFICIENCY COUPLINGSHardLine’s telescoping coupling design nests one tube into another to minimize air-leakage in low and high pressure applications.

LOW LEAKAGEHardLine’s easy-to-use ratchet coupling reinforces and seals each connecting joint to create a highly efficient coupling system.

SYSTEM PRESSUREHardLine Ducting is structurally supported and designed to withstand various positive and negative, low and high pressure applications. Contact our Sales Engineers for design specifications.

SAFETYFIRE RESISTANTHardLine Ducting is fire resistant and passes CAN/CSA M427-M91 and MSHA CFR30 standards, as well as other local FR regulations. Please contact our office for certificates.

COLOR HardLine Ducting is manufactured using a safety green color for high visibility.

IDENTIFICATIONProducts are identified with diameter, length, airflow direction, manufacturing date and work order number.

WEIGHT AND HANDLINGHardLine is 70% lighter than steel and 30% lighter than fiberglass pipe.

QUALITY MAKES A DIFFERENCE

ENVIRONMENTAL RESPONSIBILITYREUSABLEHardLine Ducting can be reused as required. HardLine Ducting is easily dismantled for relocation or storage.

RECYCLABLEEPVS currently reprocesses its RigiFLEX-FR™ waste material into new HardLine Ducting and Accessories. Our objective is to expand this program to include HardLine end-users.

REDUCING CARBON EMISSIONSHardLine Performance Ducting compresses down smaller than steel or fiberglass for transportation and storage. The carbon footprint is significantly lowered when transporting HardLine compared with other rigid products. The chart below is an example of area required to ship 42”dia (1070mm) x 80ft (24.4m) of duct.

COST SAVINGSENERGY REDUCTIONHardLine Ducting offers energy reduction by increasing airflow. In lowering the coefficient of friction by more than 40% and reducing air-leakage, through high efficiency couplings, HardLine provides efficiency gains and lowers air resistance to reduce energy costs.

FEWER FANS – MORE AIRHardLine Ducting requires fewer fans than steel or fiberglass duct to generate and deliver air throughout a mine or tunnel.

FASTER INSTALLATIONHardLine offers a quick-to-install system that requires straightforward skills to deploy.

REUSABILITYHardLine Ducting can be easily disassembled and reused.

FREIGHT AND LOGISTICSHardLine Performance Ducting ships compressed or as a flat sheet, allowing product to be shipped at a lower cost and with less carbon emissions than other ventilation options.
