Since inception, Snow Economics, Inc. has installed snowmaking products at more than 420 ski areas around the world. All of the products developed and manufactured by Snow Economics, Inc. utilize energy efficient HKD air / water technology.

Some of the countries where HKD Technology is in operation are the U.S.A., Canada, Korea, Japan, China, Austria, Switzerland, France, Italy, Germany, Spain, Sweden, Norway and New Zealand.

Although Snow Economics, Inc. was incorporated more than 15 years ago, HKD Technology was conceived some 20 years prior by Herman K. Dupre. Mr. Dupre, founder of Seven Springs Resort in Western Pennsylvania and inventor of the patented HKD Tower system spent numerous years developing and refining his technology in its practical application, on the mountain. With the HKD Tower System in place, Seven Springs has the unprecedented ability to make snow at the rate of 30,000 gallons per minute using only 26,000 cubic feet per minute of compressed air. With these capacities, the resort is able to blanket 400 skiable acres of terrain with 12 inches of snow in approximately 48 hours.

HKD Products:

HKD offers a full range of snowgun towers and accessories to fit any snowmaking application.

The S Series raises the bar for air/water snowmaking technology. The multi-chambered, completely modular Tower can utilize our Patented double valve base configuration or the rugged fixed flow base block with any of efficient snowgun nozzle designs. S Series Towers can be mounted on the S Fixed Bracket at the side of a trail or sled mounted to patrol a variety snowmaking locations. The modular design of the S Series allows for technology upgrades and streamlines general maintenance and repair work. Enjoy the peace of mind that your snowmaking investment with HKD Snowmakers can evolve to meet the ever-changing needs of your resort.

Snowmaker	Distribution	Applications	Description
SV10 Impulse
		Wide Trail Narrow Trail Steep Trail Terrain Park Base Area Real Estate Access	The The BRAND NEW HKD SV10 Impulse marks yet another milestone in the development of HKD Low-E Technology. The Impulse's unique design incorporates Snow Economics' dynamic Low-E air control technology (patent pending). The Impulse gives the snowmaker the ability to manage snowgun performance at all temperatures by adjusting air AND water flows, simultaneously. The Impulse is essentially two low-e tower snowguns in one. In the high temp mode, the Impulse uses a little more compressed air to cover your most critical, early opening terrain under marginal snowmaking conditions. As temperatures fall, the Impulse is capable of shifting gears (while operating) to its outrageously efficient, low airflow, low-energy consumption mode. The revolutionary air flow adjustment capability of the Impulse allows for snowmaking performance and efficiencies unattainable by competing products.
SV10201
		Wide Trail Narrow Trail Steep Trail Terrain Park Base Area Real Estate Access On-Board Compressor	The SV10201is a time tested, proven performer. It is capable of low flow, high temperature performance with a smooth transition to high flow, low temperature production . The SV10201 incorporates our most advanced valving technology capable of four levels of water flow, thus allowing the SV10201 to perform optimally in the widest range of temperatures through valving of the (8) water nozzles.
SV6400
		Wide Trail Narrow Trail Steep Trail Terrain Park Base Area	With a broad deposition pattern the SV6400 is ideal for mid-width trails and open areas. Capable of operating at water pressures of 200 psi and higher it can be used on any part of your mountain. The ability to valve the back two nozzles individually gives you the flexibility to maximize the operation of the SV6400 at a variety of temperatures without shutting down to change nozzles.
SX6400
		Wide Trail Narrow Trail Steep Trail Terrain Park Base Area Real Estate Access On-Board Compressor	The SX6400 is specifically designed to project snow with pinpoint accuracy. Its focused, directional throw makes the SX6400 ideal for narrow slopes, real estate access and Nordic trail applications. The ability to valve the back two nozzles individually gives you the flexibility to maximize the operation of the SX6400 at a variety of temperatures without shutting down to change nozzles.
SV6201
		Wide Trail Narrow Trail Steep Trail Base Area On-Board Compressor	The SV6201 is a fixed flow low cost snowmaker with internal nucleation. This produc t is ideal for secondary terrain. Itsbroad deposition pattern is ideal for mid-width trails and open areas. Low cost and lightweight, the SV6201 is a very affordble solution for secondary terrain. Operating at water pressures of 200 psi and higher it is available in 10ft and 20ft lengths and can be mounted trailside or placed in the trail using one of the HKD portability accessories.
SV4400
		Wide Trail Narrow Trail Steep Trail Base Area	The SV4400 is a fixed flow, low cost snowmaker with external nucleation. Low cost, light weight and a broad spray pattern makes the the SV4400 is extremely versitile. Operating at water pressures of 200 psi and higher it is available in 10ft, 20ft and 30ft lengths and can be mounted trailside or placed in the trail using one of the HKD portability accessories.
SX4400
		Wide Trail Narrow Trail Steep Trail Terrain Park Base Area Real Estate Access On-Board Compressor	The SX4400 is specifically designed to project snow with pinpoint accuracy. Its focused, directional throw makes the SX4400 ideal for narrow slopes, real estate access and Nordic trail applications. Essentially, the SX4400 incorporates all of the advantages of the SV4400 with a very controlled deposition area.

Super Blizzard

HKD has taken portable, self contained snowmaking to the extreme with the new Super Blizzard. This machine is for the serious snowmaker with a real job to do! The Super Blizzard uses the patented "HKD" snowmaking technology developed by Snow Economics, Inc. and used by ski resorts around the world. These resorts rely on our technology to get open and to maintain a quality snow surface on their trails throughout the winter. So why not have that same reliability and capacity for your snowmaking needs!

The Super Blizzard can make snow at the rate of 35 Gallons per minute (GPM) and can pull water from a pond, lake or river, or take water from a fire hydrant. Components include two Electric motors 480 V/3 phase (or 600 V) which drive the water pump and air compressor. All components are designed for the long haul, capable of running uninterrupted for days at a time. The machine is efficiently laid out in the protected environment of a 6' x 10' enclosed trailer, road ready with ball hitch. This allows for easy transport to and from the action. Also included is the snowgun and aluminum sled as well as all hoses to connect to your water source and then to connect to the snowgun.

Generally start up temperature is +/-28 Deg F depending on the humidity and water temperature. The snowgun has three flow rates which are controlled by two ball valves at the base of the snowgun.
