Greenhouse Unit Heaters Redefined
The revolutionary tubular heat exchanger inside the Lennox LF-24 series of greenhouse heaters ensures you years of performance and high efficiency. Combustion is precise because of special "in-shot" burners and fan assisted exhaust. Equipped with a TrueLeaf Combustion Air Separator, it's bullet-proof.
Give Your Greenhouse a Clean Advantage

TrueClear is the safest, most efficient chemical-free water purification system available.
It economically purifies and disinfects any water source including wells, ponds or lakes.
TrueClear works its magic by means of an electrical field that turns O2 molecules into O3
molecules, or ozone. Untreated water is forced through tube into a mixing tank where ozonated
water mixes thoroughly with the untreated water. Pathogens are destroyed on contact and harmful minerals are separated out for easy filtration. Timed backwash regularly cleans the filter media and the entire process is flow-activated, causing no pressure drop or flow restriction. System only runs when water is being used and automatically shuts off when usage stops saving energy and money in the process.
What is TrueClear?
The TrueClear system was engineered after discovering the problem issues related to drinking water.
- The patented ozone purification system is chemical-free and provides the most efficient method for purifying and disinfecting water known to modern science.
- A proven system design: ozone should be sold from a complete systems approach. The TrueClear system includes all required components.
- A modular system designed for easy service and a small footprint.
- Designed so no flow restriction or pressure drop is experienced.
- Flow activated, not tied to a well pump control. The system continues to run for a preset period of time to ensure that the last water in gets fully treated before shutting off. This system works as well on municipal water as it does on well water. It can be installed anywhere in the plumbing after the pressure tank.
- Expandable: add to the system if an increase in demand or flow is required.
- State of the art design.
The bottom line: TrueClear is without question the first complete system design to bring high quality water to the grower without the maintenance and design issues of traditional ozone systems.
Why use Ozone?
Ozone is:
- The best disinfectant available: it kills bacteria, virus, protozoa, molds and fungi.
- The best oxidizer available: it is the best technology for oxidizing Iron (Fe, red stains), Manganese (Mn, black stains), Hydrogen Sulfide (H2S, rotten egg odor), arsenic, molds and fungi, and many other contaminants.
