Linde High-Capacity Returnable

Elevate Your Gas Calibration Productivity

Linde’s High-Capacity Returnable (HCRT) cylinders offer high-capacity calibration gas solutions in a convenient size.

Linde’s HCRT 300L and HCRT 60L transportable cylinders offer industrial hygienist professionals and technicians a calibration gas delivery solution that increases productivity and reduces inventory costs. These lightweight, high-capacity, transportable cylinders are plug-and-play capable with your gas detector instruments and easy for you to carry.

HCRT – The Sustainable Choice

The use of Linde’s transportable cylinders assists in reducing your carbon footprint because our sustainable cylinders stay out of landfills, unlike standard transportable disposable cylinders. In addition, our line of aluminum reusable cylinders, with no return costs, saves you money by eliminating disposal fees.

Linde’s Certifications

Our manufacturing facility is ISO 9001:2015 certified and ISO 17025:2017 and ISO17034:2016 accredited. This facility follows the most accurate gravimetric blending methods, which are traceable to the National Institute of Standards and Technology (NIST). Each cylinder comes with its own Certificate of Analysis.

Flow Regulators for Use with HCRT Cylinders

When the regulator is first installed, the gauge will remain in a passive mode reading 500 psig. Once the gas content drops slightly below 500 psig, the gauge becomes active and indicates the actual gas content. Linde recommends reordering a new cylinder when gas is at or just below 400 psig. A Linde Territory Manager can provide further support on how to operate your cylinder, how to order regulators and how to use our Strip & Ship cylinder return program.

100 Series Flow Regulator

Designed to maintain constant flow rates so you get accurate monitor calibrations even as the cylinder pressure drops.

Preset Flow Regulator

Designed as an economical means to provide the correct gas flow to instruments for calibration and is preset to flow 0.5 lpm.

Linde’s Strip & Ship™ Program

Linde’s patented (U.S. Patents Re 45,572 and No. 8,162,587) Strip & Ship program allows the technician to return the reusable aluminum transportable cylinder to Linde via prepaid Federal Express label. After it is returned, the cylinder will undergo a proprietary reconditioning process to ensure quality and shelf life stability for future reuse.

How does Strip & Ship work?

When the empty cylinder is ready for return, ensure that all gas has been purged in a safe and well-ventilated area, strip off the content label, and arrange with FedEx for pick up or deliver to a FedEx location for return shipping. Follow the easy Strip & Ship steps below:

  1. Make sure gauge reads zero.
  2. Strip off content label to reveal prepaid return label beneath it.
  3. Provide prelabeled cylinder to carrier to easy return.
