Standard configuration

Heavy duty heat exchanger coil and casing, manufactured from corrosion resistant materials.
An acrylic coating is applied to the cooler coil for added protection against harsh environments. All ABT units are fitted with an adiabatic booster section that can be used to pre-cool incoming air on hotter days. A wide range of heat exchanger configurations is available to maintain precise cooling conditions, no matter the climate.

Up to 20 fans in 1 or 2 fan rows. ErP compliant EC fan motors with external rotor, protection class IP 54 according to DIN 40050. EC power supply 380-480/50-60/3 with integrated thermo contacts to provide reliable protection against thermal overload.

How it works

Adiabatic technology with zero moisture leakage

Alfa Laval Abatigo prevents any water drift to the heat exchangers, keeping them completely dry – preventing scaling, corrosion, and dangerous waterborne diseases such as Legionella. The cooler is designed to usually work in dry mode, when the adiabatic mode is activated, it works as follows:

  1. High-temperature ambient air passes through lower adiabatic chamber.
  2. Inside this chamber, nozzles spray the coil with a fine mist of water from a separate source.
  3. The air is cooled due to humidification, prior to contact with heat exchangers.
  4. The chamber’s design prevents any water drift outside the chamber when the cooled air travels to the heat exchanger.
  5. Digital control system continuously adjusts the amount of water sprayed to ensure consistent cooling.
