Grain & Biomass Storage and Drying / CHC Burners / Harvest CHC Burners

Harvest CHC Burners

Adding a Harvest Automatic Constant Humidity Controller (CHC) to your existing crop store you can effectively dry 24 hours a day during any weather conditions.

The CHC system has a proven record of accuracy, efficiency and economy there are thousands of units in use. Its the easiest and surest way of turning bulk storage systems into reliable drying units.

Economical drying rates are achieved because the CHC system gives continuous drying all the time the store fan is running. The CHC is effective on all usual combinable crops.

A large range of models are produced, from 200,000 to 4,000,000 BTU / hr - to suit all types of fans. Each one features purpose - built solid state electronics and plate - type burners ensuring accurate, trouble - free performance.

Features

Plate-type Burner Head

Harvest's purpose-built burner head has been developed to give maximum possible heat output and the most efficient combustion of LPG. Its size is as compact as possible keeping the CHC unit easy to handle, portable and small enough to be installed into majority of bulk stores.

Fan Technology

Harvest's designers have successfully matched fan size to burner output. This gives the maximum air output with minimum electricity consumption and the lowest noise levels.

Electronic Controls

The total CHC control system is conveniently housed. It incorporates a large digital display showing humidity or temperature levels.

A computerised programme of heat output relevant to ambient humidity gives you a very accurate control system that's been verified by independent assessors. This system is common to all CHC models.

Safety Regulated

All Harvest equipment and components are manufactured to current regulations and each CHC unit carries the CE mark.

This guarantees that each CHC model has the highest specifications and top - quality components.

Product Types

CHC Onion Burners

High capacity Fans in onion stores have led to the development of multiple units with a single master unit controlled by one sensor within the main air - duct.

Harvest Installations can supply multiple units on purpose built frames for either grain stores with multiple fan units or onion drying plants with their high capacity fans and large air ducts.

Harvest Advance Controller

To give a complete drying and conditioning system, Harvest have designed an automatic fan control unit, using the same humidity or temperature sensors that control the burners, fans can be programmed to run between upper and lower limit controlled by either the humidity or temperature sensor.

This is invaluable when cooling stored crops and eliminating the possibility of 'rewetting' grain or running fans when ambient conditions are not suitable.

Harvest Maxi-Stirrer

As more farmers use the Harvest Maxi-Stirrer as a batch dryer employing high temperature air for faster drying, larger models of CHC are used to give the necessary temperature lift, aisles multiple units.

The larger models give the required temperature control in onion stores where exceptionally high volumes of air are required. Please get in touch for further details of the Maxi-Stirrer and crop drying fans
