The Remarkables Ski Field is one of New Zealand's premier ski fields, located at a longitude of 45.05 degrees South, elevation 1,586 m and situated near the North end of the Remarkables range. The base building has approximately 2,500 m² of heated outdoor patio at a density of 200 W/m². The heating of the patio matches the needs and requirements to prevent the surface accumulation of ice in a modern and highly efficient way.
The Challenge:
Property damage and increased injuries due to winter conditions
In recent years there have been plenty of news stories about human and financial costs caused by harsh winter weather. Property damage, increased maintenance expenses, productivity losses, rising insurance premiums, personal injuries and even worse. Installation of electric heating for melting ice and snow ensures a steady solution to address cold-weather-related problems. The main purpose of electric heating is to melt and remove snow and ice from ground surfaces. The Remarkables Ski Field also faces these challenges.
Solution:
Electric heating system connected with BMS
The electric heating system was wired as 22 x 230 V zones and controlled by multiple DEVIregTM 850 / ECtemp 850 controllers. The controllers work in conjunction with the base building's BMS and include a manual/auto bypass control. It enables the operator to select auto, manual on, and manual off. This had been a design requirement that permits short notice manual changes in the event of rapidly changing weather conditions.
Result:
Prevented surface accumulation of ice
A snow and ice melting system was installed on the outdoor patio of the base building, divided into 22 zones. A mixture of 3 x 680 W and 4 x 110 W DEVIreg™ Snow 30T / ECsnow 30T cable elements were fixed to reinforcing mesh which was seated on 50 mm chairs onto which 100 mm concrete slab was poured.
