MAC EVO / condensation
An electric heat pump removes moisture from the air by condensation and uses the recovered heat to reheat the process. Drying is based mainly on air circulation inside the chamber.
INCOMAC / TIMBER DRYING KILNS
The right climate.
Ready timber.
INCOMAC drying kilns combine the drying chamber, energy source and software control. From smaller JUNIOR versions to systems for sawn timber, lamellas and beams.

CHOOSE THE ENERGY SOURCE AND PROCESS
INCOMAC offers more than one drying method.
ICD / TAG / conventional
Moisture is removed by controlled air exchange. ICD uses an external heat medium; TAG its own heating system with a burner. In the current programme these versions are also presented as JUNIOR.
MAC_Hybrid / combined
Combines a heat pump and an external heat source. A sensible option when you want to balance available electrical and thermal energy with process needs.
Condensation describes the method of removing moisture; conventional drying mainly uses exchange of moist air. The hybrid version combines both principles.
ANIMATED COMPARISON
Air carries heat and moisture.

Stack preparation
We stack the wood and prepare the measurements for the selected cycle.

SMALL DRYING KILNS IN THE FOREGROUND
JUNIOR / a chamber tailored to smaller production.
Classes 5 / 10 / 20 m³
JUNIOR is a programme for smaller quantities of timber. The manufacturer envisages installation outdoors or inside the plant, including integration into the material flow. Loading options include rails and a trolley.
- MAC JUNIOR
- Condensation system with heat pump
- ICD JUNIOR
- Hot water, steam or another agreed heat medium
- TAG JUNIOR
- Heating with a burner depending on the fuel and execution
- MAC_Hybrid JUNIOR
- Heat pump combined with an external heat source
5, 10 and 20 m³ are the published classes of the JUNIOR programme. We match the net timber quantity, required clearances, connections and loading method to your stack.
HOW IS THE CHAMBER BUILT?
Structure, insulation and access are part of the technology.
Load-bearing structure
INCOMAC uses aluminium profiles and stainless steel fastening elements resistant to corrosion. The structure and equipment are adapted to the loads, temperatures and conditions at the installation site.
Insulated enclosure
Modular panels with aluminium cladding and selected insulation reduce heat losses. Different types of insulation are available; the choice depends on process temperature, installation and other requirements.
Doors and material flow
Front or tunnel loading, various door designs, and trolleys and rails. We choose a material path that makes sense for your plant.
Ventilation and conditioning
Fans, frequency converters and, if needed, high-pressure humidification adjust the climate. Functions and equipment size are determined according to the programme.
Connection to plant energy systems
We check the available electricity, boiler room and possibilities for heat recovery. Connection to a solar power plant or other sources requires calculation of the complete installation.
SOFTWARE AND CONTROL
Measurements help maintain the correct regime.

iDry / STOP & GO
Based on measured humidity and temperature, the programme adjusts ventilation and the balance of operating and pause periods. Decisions are based on the state of the material, not just on identical time intervals for each batch.
The operator prepares the material and the programme, while the system carries out the control. We check the available functions for the selected control system.
Incotech / connected services
The service programme includes remote diagnostics, support during cycles, training and production monitoring options. INCOMATH is the manufacturer's tool for benchmarking and consumption optimisation.
INCOMATH is not automatically included in every chamber. Access, licences, monitoring and the service package are part of the agreed solution.

ENERGY EFFICIENCY
Less losses. Better consumption control.
Heat recovery
The heat pump uses the cold side to remove water and the hot side for heating. In air-exchange designs, recovery transfers heat from the outgoing air to the incoming air.
Ventilation as needed
STOP & GO, efficient motors and frequency converters reduce unnecessary operation. Each option is selected according to the material and the process.
Measurement before promises
We compare consumption on a representative batch. INCOMAC offers analysis of electrical and thermal energy as well as monitoring of the effects of improvements.
What do the published saving percentages mean?
For STOP & GO, INCOMAC states up to 50% electricity savings compared with a standard cycle, and for recovery up to 30% thermal energy savings. These are two different comparisons; the percentages are not added together. The result depends on the timber, weather, regime and equipment.
MAC EVO uses R513A refrigerant. The manufacturer compares its global warming potential with the previous R134a. This comparison of refrigerants does not mean the same percentage reduction in total consumption or all emissions of the drying kiln.
