The Heat Ranger is an agricultural frost management system designed to protect New Zealand crops from crippling frosts, right down to -6°C. Bentech Limited was fortunate enough to be approached by Fred Phillips, the Director of Heat Ranger, and asked if we would develop and build the electronic control system for the machine.
The machine involves processing data from temperature sensors (both in the field and in the machine itself), rotational sensors, battery and fuel levels and even an accelerometer, in order to control the LPG burner, turret rotation, leg heights and heating distribution patterns etc. The system is smart enough to predict a frost and turn on in advance, and communicate via the internet to upload logged data, events and diagnostic information.
Bentech Limited also provided website design services, and continue to provide ongoing product development and in-field servicing.
The Heat Ranger frost management system offers a cost-effective solution for covering a hectare, both in terms of setup and operating expenses. Moreover, it’s eco-friendly, operates quietly, and delivers outstanding results. Compared to other frost management systems, Heat Ranger has a clear edge, making it a smart investment for enhancing your crop’s climate.
The Heat Ranger sets itself apart from other frost management systems by elevating the temperature of the air beneath the inversion layer, which effectively minimises the likelihood of frost formation. With its exceptional rotational air distribution management, this system can safeguard your crop and accommodate a variety of field shapes.
Farmers worldwide trust the Heat Ranger to provide superior frost protection for their crops.
“From the very beginning of the development of the Heat Ranger frost fighting machine it was obvious that we were going to need a sophisticated and reliable electronics package to be able to operate remotely and measure the key weather parameters and the machine’s operation in harsh conditions.
Bentech was able to support us through the early stages and has developed a total package that controls all aspects of the machine, monitors its performance against the background frost conditions in real time and provides performance and service records for each machine.”
