Freight Savings
For large heater orders over $10,000, freight savings are available by contacting our sales team at 1-888-281-9337.

Model PDP Power-Vented Unit Heaters: The PDP (propeller) High Efficiency II gas-fired unit heaters feature a blower-powered vent exhaust. This vent forces heater exhaust fumes outside of the heated structure, and allows the heater to be vented vertically or horizontally. Horizontal venting prevents heat from escaping out of the vent pipe when the heater is not running, which is especially important in greenhouses.

Standard Features

  • 80% thermal efficiency, maximizing seasonal efficiency through the use of a collector box and power exhauster.
  • Power exhaust that can be rotated 180 degrees.
  • 100% shut-off, intermittent pilot-ignition system with continuous retry.
  • Field convertable from natural to propane gas.
  • Safety pressure-switch to assure safe venting conditions.
  • Designed to use the smallest diameter vent pipe possible.
  • "Wing" screws so that the bottom pan can be dropped without a screwdriver.
  • Certified to 0.5" W.C. external static pressure.
  • A level hanging mechanism for easy field adjustments.

Excellent Can Opener – Safe, Effortless, and Smartly Designed!
I’m so impressed with this electric can opener! From the moment I took it out of the box, it was incredibly easy to use—just one touch and it does all the work for you. What really sets it apart is how it opens cans with a smooth edge, so there's absolutely no worry about scratching yourself or dealing with sharp, jagged lids. That’s a huge relief, especially for someone like me who cooks often and has had accidents with traditional openers in the past. The design is compact and sleek, making it easy to store in a drawer, and it feels solid and well-made in the hand. It’s also surprisingly quiet while running. I’ve used it on all types of cans, and it works like a charm every time. Honestly, I didn’t expect to love a can opener this much, but it makes such a difference in the kitchen. If you're thinking about getting one, this is 100% worth it!

Effortless Can Opening – A Game Changer in the Kitchen!
I absolutely love this Automatic Electric Can Opener! It makes opening cans so much easier and completely hands-free. No more struggling with manual openers or sharp edges—this gadget does all the work for you with just the push of a button. The smooth edge cutting is a huge plus because it keeps my family safe from accidental cuts. It’s lightweight, easy to use, and works perfectly with just a couple of batteries. I especially appreciate it when I’m multitasking in the kitchen because it saves so much time and effort. Honestly, it’s a must-have tool for anyone who cooks regularly, and it would be a great gift for seniors or anyone with hand pain or arthritis. Highly recommend—it has truly made my kitchen life easier!
