Hot water drilling equipment is another of our product lines. This includes the smallest hot water drilling system available for drilling holes in sea and glacial ice. This system’s boiler and pump unit fit into a latched shipping-field container only 36 cm (14 in.) wide, 53 cm (21 in.) high by 58 cm (23 in.) long. The box and boiler-pump unit weigh about 64 kg (140 lbs). The pump is rated at 8 liters per minute (2.1 g/min.) and the boiler can produce water of 80 to 90^oC (175 to 195^oF) depending on flow rate and supply water temperature.

This small system is ideal for shallow drilling at remote sites where shipment weight and portability are of concern. this system requires power from a 2 - 3 kw electric generator.

A three section stainless steel drill rod is standard. the upper section (75 to 100 cm long) is a heavy walled shaft, the mid section (20 cm) is tapered and the lower section (7 - 10 cm) is the tapered tip. The tip’s discharge orifice size depends on operator’s preference. Tips can be provided with various size orifices. Additional upper shaft lengths can be provided which thread into each preceding section.

High pressure hose is available which is specifically SAE rated for hot water use at 121^oC (250^oF) continuous and 135^oC (275^oF) intermittent flow. (We do not provide high pressure hydraulic hose as these hoses are not rated for high temperature water use). The customer selects hose length(s) and either 0.95 cm (3/4 in.) or 1.27 cm (1/2 in.) I.D. hose. The former weighs 0.33 kg/m (0.225 lbs/ft) and the latter weight 0.48 kg/m (0.32 lbs/ft). Customer also selects either plated steel or stainless steel MPT (English pipe thread) hose end fittings.

Hot water drilling systems are tailor made to fit customer needs.

All boilers can use number 2 fuel oil, JP fuel or kerosene. However, the former is the preferred fuel.
