What is a Jet-Ready Precooler™?

...Is it just another "two fans on a stand"?  Hardly!

Our Jet-Ready has double the airflow of a typical farm-built unit,

and also of many many built-in plenum wall systems,

- especially if they are 20 or 30 years old; motors and props have come a long way -

empowering you to precool twice as fast! (typical result, yours might be faster!)

The Jet-Ready™ Precooler is a forced air cooling tunnel, preassembled, fully-wired, tested, and ready-to-use. It includes powerful, energy-efficient special-design fans, foam pads and tarp, and all electrical controls, mounted on a Carboline-coated heavy-duty structural steel frame. (The tarp is field-attached with 3 spring clips.)   Also, because we use a soft-start, there isn't any inrush current nor start-up lock-rotor amps, which is great for your electrical system and meter.  SO, you ask, how much space/room do I need? Click here to see drawing of typical floor plans.

There is also a Variable Frequency Drive (VFD) for soft starts and stops, as well as motor speed control.  Includes motor starters, fused disconnect, and 25-foot long cord. The Jet is placed in an existing cold room, which supplies the refrigeration capability.  Easy to use, watch video (1 minute 8 seconds.)

What DON'T You Have to Do?

As opposed to the traditional way where you get a building permit, pour a concrete base, erect a plenum wall, cut holes in it, buy fans from somewhere, mount the fans, provide starters and disconnects, wire them, etc.  No construction, no permit, no mess, and no carpenters, laborers, or helpers wandering around your facility.

Our Customers Say...

"If you are in the cold storage business, you have to have a Precooler. We do a lot of strawberries, and most of the time they come in cold enough.  But every now and then you get a hot load, and you have to be able to cool them back down in a hurry.  The Jet Precooler is perfect for us."  N.S.

"It is a lot easier and faster to take the Jet Precooler to the produce, than it is to move 10 or 20 pallets to a built-in precooler." M.B.

"Your Jet Precooler exceeded our expectations.   We are very pleased with the positive effect it has had  on our fruit.  It has run flawlessly since the day it was fired it up " M.L.

“It is so flexible, ten seconds later it’s in a different section of the facility doing a different function.”  M.A.

"The fact that the units are portable gives this solution a huge advantage over "bunker wall" cooling solutions"  P.E.

"The Jet Precooler cools the yogurt much more rapidly than our old method."   J.R.

"Jim, all I can say is, your fans move an awful lot of air, it's unbelievable."   R.L.

"We use a Jet to cool down avocados after ripening, in about 4 hours."   F.M.

""The unit is working perfectly.  I'm pulling heat out of the product after it is picked."   D.D.
