Techspray's New Eco-Friendly Duster and Freeze Spray... High Performance Without Global Warming Impact

Share Article

New Techspray Renew Eco-Duster and Eco-Freezer are formulated with new HFO-1234ze propellant. They have the same performance as traditional dusters and freeze sprays, but at a fraction of the global warming potential.

New eco-friendly duster and freeze spray!

Techspray's new Eco-Duster and Eco-Freezer are examples of how we are blazing the trail for innovative, eco-friendly solutions.

Introducing Techspray Renew Eco-Duster (part #1580-10S) and Eco-Freezer (part #1583-10S), the latest additions to Techspray’s eco-friendly product line. Formulated with new HFO-1234ze propellant, they have a fraction of the global warming potential (GWP) of HFC-134a based products.

Eco-Duster and Eco-Freezer are drop-in replacements for HFC-134a equivalents. They are non-flammable, odorless, have low toxicity, and similar velocity and freezing temperature as traditional dusters and freezers.

HFO-1234ze has a GWP of 6, compared to HFC-134a with GWP of 1300, and HFC-152a at 140. GWP is measured in relation to CO2, with CO2 GWP set at 1.

Because HFO-1234ze is lighter than HFC-134a, there is more volume and blasts per can.


  •     Global Warming Potential (GWP) less than 1/100th of HFC-134a
  •     8% more volume (sprays) per can vs. HFC-134a
  •     Non-flammable
  •     Non-ozone depleting
  •     Zero residue & no odor

Dusters blow away dust, microscopic contaminants, lint, metallic oxide deposits and other soils that can cause heat build­up or shorts in sensitive electronics. Freeze sprays use rapidly evaporating liquid that super-chill isolated areas. They are used as troubleshooting aids for intermittently faulting capacitors, resistors, semiconductors, and other defective components. They also increase visibility of cold solder joints, cracks in printed circuit boards and oxidized junctions.

Eco-Duster and Eco-Freezer are fully compliant with California CARB requirements. Also compliant with European REACH and WEEE initiatives. It does not contain RoHS restricted substances, SVHC listed substances, or halides.
