marketplace | continued EXTEND BATTERY LIFE SAFE HEAT Provide heat without the danger of combustion with Wacker Neuson Climate Technology's HIF 690 and HIF 1200 flameless indirect-fired heaters. Using a diesel engine to generate heat, the heaters completely isolate the flame from the surrounding environment, avoiding combustible mixes created by applications such as oil and gas, underground and aboveground mining and restoration. The technology works by drawing cool ambient or recirculated air through the body of the heater and then through an exhaust heat exchanger and radiator, and then further across the engine and heat plate. Upon being pushed out through the shear plate oil heat exchanger and then discharged through the outlet duct, the heaters deliver a max air output temperature of 250 degrees Fahrenheit, with a max temperature rise of up to 150 degrees Fahrenheit. The HIF 690 can heat up to 1,000,000 cubic feet with a 686,000-Btu per hour max input, delivering up to a 4,000 cfm airflow at a 3.5-inch static pressure. The heater can be equipped with a standard 20-inch or optional dual 12-inch outlet. Powered by a Cummins Tier 4 interim-compliant diesel engine, the HIF 690 can operate for more than 20 hours per tank of fuel. 22 December 2013 | EquipmentWorld.com Boost productivity with PowerHouse HD dirt housings from Ditch Witch, which offer extended battery life, electronic protection and a lid system that enables adapting to downhole conditions. An electronic cavity for beacons and sondes is rotated to the 3 or 9 o'clock position, a placement that allows production of heavy-duty housings up to 25 percent stronger than housings with the door in the weakest position (12 or 6 o'clock) when drilling. A Beacon Buddy device protects beacon or sonde when it gets overheated or plugged downhole and melts to regain fluid flow, minimizing damage to the electronics. A check valve system minimizes fluid loss while eliminating backflow into the system to prevent nozzle plugging. An open cavity between the beacon antenna and the steel in the housing extends battery life by up to 22 percent, and recessed nozzles assist the bits with easily cutting into the soil.
