Hamilton Unveils New System Separator

Hamilton Engineering, manufacturer of the EVO product line, has released its newest low-loss header: the Hamilton System Separator. The system separator allows for an infinite number of heating zones and loads with precise water temperature control, while maintaining boiler efficiency through turbulent flow. It functions as the heating system’s hub, removing air, separating flows and acting as the primary dirt and sludge separator. The system also eliminates pump conflict, extra boiler room plumbing and protects a grower’s boiler from fluctuating pressures, thereby increasing a boiler’s efficiency.   For more information on the new system separator, call Hamilton Engineering at 800-968-5530, e-mail [email protected] or visit HamiltonEngineering.com.

Heating Symposium Emphasizes Efficiency

Modine Manufacturing Company produces heating systems for an assortment of industries, including automotives and schools. Modine is also a greenhouse heating systems manufacturer, and top of mind for the company’s leaders in all units it manufactures is energy efficiency. As part of an energy-efficiency symposium last week, Modine invited three public officials to present on the importance of energy efficiency. Wisconsin Lieutenant Governor Barbara Lawton was one official on hand, and she called energy efficiency a high priority for greenhouse growers. “Energy efficiency is the first essential step toward [reversing] global warming,” she says. Lawton also mentioned Wisconsin is trying to initiate retrofit heating efficiency loans for users of energy-efficient heating systems like Modine’s new Effinity93 gas-fired unit heater and similar products on the market. Another official, Rich Hackner of Focus On Energy Wisconsin, emphasized the cost savings growers will see if they take energy efficiency seriously. Seventy to 80 percent of all energy […]

Monitoring Greenhouse Energy Effectively

The iGrow 400/800 series of controllers from Link 4 Corporation is designed specifically for easy transition in existing greenhouses using thermostats or early-generation controllers, while providing advanced control capabilities and affordability. The unique energy-use monitoring system gives growers real data on energy used by individual pieces of equipment for heating and cooling systems, showing energy cost savings and return on investment (ROI) for the controller. This is something thermostats or other controllers cannot do. Once a grower reaches his or her ROI with the controller, it will continue to show energy cost savings going forward. While traditional thermostats have often been used by growers to provide simple temperature control only, the iGrow 400/800 controllers offer a more advanced control over a wider range of equipment, such as: –Exhaust fans –Pad Pumps–Pad Louvers –HAF Fans –Fan Jets –Unit Heaters –Perimeter Heating Systems –Vents & Curtains –Other Equipment Each piece of equipment’s […]

Modine’s Latest Heaters Improve Efficiency

The Effinity93 from Modine Manufacturing Company has a full line of six models ranging from 135,000 to 310,000 BTUs per hour. All six models operate at 93 percent efficiency, giving growers a more efficient way to heat greenhouses so they can dramatically lower their energy bills, decrease fuel consumption and keep their environments controlled for optimal comfort and safety. “We developed the Effinity93 line to provide commercial HVAC users an option that meets the energy needs of tomorrow, drives down energy costs and creates a substantial return on investment–benefits that are clear to the end user,” says Matt McBurney, director of Modine’s commercial products group. “We strived to include standard benefits that would make it an attractive and convenient addition to any building project or pre-existing facility.” The Effinity93 features Modine’s Conservicore technology, a high-grade stainless steel secondary heat exchanger specifically designed to withstand the acidic condensate that is a […]

10 Tips For Improving Heating In The Greenhouse

Winter drafts. They’re enough to send chills down your back, especially when you start thinking about possible gaps, tears and holes in and around your greenhouse. Nothing’s worse than escaping heat and losing money at the same time. What follows are 10 action items that will help keep more of your heating dollars safely in your pocket as the temperature dips. Bob Fritchen, sales manager at Modine Manufacturing Company, says it best: “Make sure the first cold blast is not the first time you turn on your system.” 1. Reduce The Space Morris Brink, West Coast territory sales manager for TrueLeaf Technologies, says, “The first thing we encourage growers to do is reduce the heated area in the early spring.” When getting crops started, cordon off a small section of the greenhouse in a pot-to-pot tight environment, rather than using an entire greenhouse range, he adds. With micro-climate heating, “You […]

Big-Time Bench Warmer

The Roll-N-Grow mat for benches and mesh for floors are new products TrueLeaf Technologies unveiled at OFA Short Course earlier this month. TrueLeaf developed the mat and mesh because many growers called the company over the last couple years asking for spot bottom heat. The Roll-N-Grow mat is made connecting tubing with holding rails that are spaced every 2 inches. Mats are ideal for most general greenhouse bench heating applications. Mesh heating for floors are designed similarly. Tubes are woven directly into a weed mat fabric and shipped on a roll just like standard ground cover fabric. Tubing is woven in on 3-inch centers, which provide even heating for gently warming crops like bedding plants, perennials in flats or potted crops produced on the floor. For more information on the warmers, click here.

Hail Storm Shreds Greenhouse Roofs

Stevens and Son Wholesale Florist is in clean-up mode this week after a Monday night hailstorm destroyed greenhouse roof coverings at its two facilities in Arvada, Colo. All coverings were made of Dynaglass, and not a single panel of it is salvageable. “It’s just a mess,” Bruce Daniel, company president, said Thursday. “We’re trying to complete one small project at a time and move forward. We’re scrambling to find materials and put a plan together. It’s a nightmare.” Daniel estimates damage well into six figures, but the operation is still in business. Twenty to 30 percent of plants were lost, and the operation expects the roof replacement process to take about six weeks. Stevens and Son will use Dynaglass coverings as the replacement material. For more on the story, click here. You can also visit the Stevens and Son website and view a slideshow of the damage sustained here.
