Pneumatic conveying with process air cooling and drying systems
Powdery substances are efficiently conveyed pneumatically in the food industry today. Hygroscopic media such as powdered sugar, whey powder or flour require a lowered dew point of the conveying air to enable conveying. The devices in the LKTA and LK series make this possible.

Water cooled process air cooler for pneumatic conveying systems
WEISSHAAR – Units and systems for air conditioning and dew point control.
With our air-conditioning systems, we can deal with virtually all air volumes as well as temperature anddew point ranges.
WEISSHAAR offers the right solutions for different tasks:
- Standardized WEISSHAAR devices in compact designs – the range of LK, LKTA or LKL process air coolers cover a wide range of requirements.
- Customized WEISSHAAR devices are primarily used in the area of process air conditioning, wherever conventional technical building systems cannot provide satisfactory solutions. In addition to a wide performance range, these air-conditioning units can be adapted to meet customer-specific factory standards or specific hygiene requirements.
- For air conditioning in the low dew point range (<4°C), an additional drying step is required in addition to conventional cool drying. After the pre-drying stage, the process volume flow passes through an adsorption dryer, which is already integrated in the system.
The WEISSHAAR quality features in air cooling and drying units
Designed for permanent continuous operation and for the heaviest loading as well as the conditioning of all temperature ranges, our units and systems are built for absolute ease of maintenance and short service down times.
Our process air coolers (LK and LKTA) are characterized by very low pressure losses and are ideal for air cooling and air drying of pneumatic conveying air flows. Of course, other applications are also possible.
The process air conditioners of the LK and LKTA series operate identically with regard to the process air. The difference between them lies mainly in the type of cooling. While the units of the LK-series are cooled by external cooling water
or cold brine, the units of the LKTA-series have an integrated refrigeration system and operate autonomously from external refrigeration supplies. The choice of whether a device of the LK or one of the LKTA-series is used depends on the conditions and requirements of the end customer. If cooling water is available on site or if several lines are to be supplied via a central WEISSHAAR liquid chiller, a solution with devices of the LK-series can be used. If there is no on-site cooling
supply at the required temperature, LKTA-series appliances are used.
