Quantity

Areas of application:

Applicable in all ambient conditions (rain, fog, heat) - with the HYGROMAT™ Automatic the humidity is controlled safely.

Medium-pressure design standard - ideal for high silos.

Safety refrigerant suitable for high ambient temperatures.

Handling and operation:

Large compressors and large heat exchangers for tropical conditions.

Quiet operation through frequency-controlled fans and acoustically optimized compressors.

Different modes of operation by means of fully automatic Siemens S7 controller microprocessor control: Quiet (whisper mode-low noise), rapid cooling (booster mode) ventilation mode (only air) and normal mode.

The whisper mode can pre-selected after selecting "temporary" (e.g. night mode).

Easy to clean - place and manholes are available for this

Effective, large-scale filters with integrated filter monitoring.

Backpressure indicator.

Viewing window in the air cooler.

Phase and undervoltage monitoring

Inspection openings in the air duct.

Speed-controlled condenser fans for smooth start during cold outdoor temperatures.

Energy and environmental balance:

Energy efficient execution due to frequency regulation and the latest motors.

Environmentally friendly safety refrigerants - without CFCs and without HCFCs.

Winter and summer thermostat to save energy.

The HYGROTHERM uses the energy from the condenser to reheat or to maintain the desired cooling humidity.

Contains sound insulation as standard (-4 dB (A))

Processing and quality:

HYGROTHERM™ heating register as standard.

Stainless steel condensate tray.

Corrosion protection through coated heat exchanger.

CE-compliant execution.

Options:

High pressure blower (HP-high pressure) for streamlined silo compartments

Protection grid against animals.

Locking supports.

Forklift pockets.

Alarm modem for mobile phone/ SMS/ ZLT

Modem for remote diagnosis/ remote display

Sound cabin for -15 to -20 dB(A).

Subject to technical changes

Since we know how grain "functions", the GRANIFRIGOR™ operates according to two successful principles:

1. Immediate cooling after grain harvest to below +13° C:

Because of this, insects go into hibernation and have no chance to spread (see fig. below). In addition, the development of molds is effectively prevented, respiration losses are minimized and due to the drying effect of the cooling process, drying expenses can be saved.

2. No ventilation with unconditioned outside air:

Humidity of the ambient air establishes a condition of equilibrium depending on the temperature. Thus, moistening occurs when moist air is introduced to dry cereal and the grain spoils. Therefore, the ventilation with fans is completely dependent on the weather. In addition, the ambient temperature is usually much too high during the harvest season.

Function:

The fan of a GRANIFRIGOR™ grain cooler draws in ambient air (see fig. below). This air is cooled in an air cooler (evaporator) to the desired temperature. The downstream HYGROMAT™ setup warms the cold air again automatically. Thus, the relative humidity is lowered and adapted to the conditions of the grain bed. Moistening, which would be extremely damaging, cannot occur. This cold and dried air is forced through the grain by the air distribution of the flat storage or the silo system. Through the exhaust vents of the storage area, the air flow passes back into the environment. With this exhaust, the absorbed heat and moisture are removed.
