- Simply Powerful Precoolers -

What, you don't need a ready-to-use portable Jet-Ready Precooler™?

That's okay.  We understand, the Jet-Ready Portable is not the answer for everybody, even if it does cost only $12 a day.  And before we invented the Jet Precooler, we were known as Global Cooling, and specialized in Design-Build Forced-Air Cooling and Ripening, and fan sales. Single fans sales and pressure cooling installations take us back to our roots.

At the heart of the powerful force that is now the Jet Precooler is the Jim Still-Designed Jet Propeller, achieved by two years of trial and error, computer simulations, and field testing.

We also offer the Jet Prop in stand-alone Jet Plenum Wall Fans™ that you install yourself .  Our standard fans are all 10 HP, for 208-230/460/60/3, with premium efficiency inverter-duty motors, and finger-safe fan guards front and rear. Precooling fans are typically deployed in pairs. We can even supply drawings so you can build your own portable precooler, if that's what you want, with your own staff, saving money. See below for more details. Contact Us for a Fan-Only Quote

We are also very experienced at Design-Build Forced-Air Cooling.  Let us know your needs, and we'll get you drawings and a proposal for your consideration. Contact Us for a Design-Build Proposal.
