The 19 models with flow rates from 500 m³/h to 200.000 m³/h offer our customers a wide selection range.
Easy Capacity Selection:
The 19 models with flow rates from 500 m3/h to 200.000 m3/h offer our customers a wide selection range. Close capacity intervals let you select the accurate flow rate for your design while the high flow rates offer economic selection flexibility.
Maximization of the Operational Efficiency:
Units driven with frequency drives let the end user change the operation range according to the need.
4EST units are designed with a wide operational range providing a full satisfaction in case of any changes on demand.
Fits All Locations:
While modular design of 4EST provides easy allocation, also mounting on site option makes every unit possible to fit every location. Mounting on site option starts with manufacturing the parts and sending them to site. Ready parts and equipments are mounted at site by our team. This option lets the customer put the units in mechanical rooms which are enclosed and impossible to carry from within the openings/doors.
Custom Production for Special Requirements:
Upon request from the customer non-standard designs and dimensions are also possible for their satisfaction.
They are made from aluminum for its light weight and extra corrosion resistance.
RAL9002 standardized side panels are composed of film coated galvanized sheet metal exterior walls and galvanized (stainless steel upon request) interior walls fully sealed in a closed structure.Rockwool ( 70 kg/m3) is used between the walls of the panel to provide heat and sound insulation. The panels are mounted tightly on to the structure with neoprene gaskets on the inside and outside to assure a leak-proof construction. The connections are made either by bolts or by special fitted joints.
Non-projecting door handles let the unit stay in the size limits as declared while reducing the risk of getting damaged. Endurable design and ability to be locked gives the customer full confidence regarding the access.
Hidden Cables & Collective Cable Connecter:
For prewired units and packaged solutions, 4EST units have a unique cabling style which protects the cables from any complications and provides simplicity. All modules are connected with special connecters holding all internal cables together collectively.
4EST - High Performance & Energy Efficiency
LIFE CYCLE COSTING of AHUs
Life Cycle Costing of AHUs with average life-span ranging from 15 to 20 years is mostly (%82-83) the energy they consume. The rest is capital expenses by %11-12 and maintenance costs by %6-7. Can Klima engineers are working on more efficient designs by focusing on energy consumption and the capital expenses.
ErP (Energy-Related Products) Directives
The goal of the ErP Directive is to protect the climate by increasing the overall share of renewable energy in the EU to 20 % by 2020 and to increase energy efficiency by 20 %. The system efficiency requirements are the premise for the CE marking and therefore must be met for use in the EU member states and devices & components exported to Europe.
The ErP implementing measure for fans defines the minimum efficiency requirements for fans with an output range of 125 W to 500 kW. When assessing whether a fan fulfils these requirements, the efficiency of the entire system is evaluated – this consists of the motor, transmission (e. g. belt drive) and impeller.
The minimum fan efficiency for fans is %63.1 and fans with below values are not available.
For heat recovery units, thermal bypass is required and air conditioning units with thermal efficiency of 73% are produced under ErP 2018 standards.
ErP - Efficiency Requirements
AHU Selection is a selection program developed by the company itself, which quickens and simplifies the selection of the AHU in terms of features and dimensions that the customer needs. With AHU Selection, AHUs become ready for production with a few minor revisions.
AHU Selection has an easy and clear interface and selection flexibility based on the values.
The projects prepared by all of the users are stored in a common database and the users can access the projects within the scope of their authorization.
Finding previous projects will be hard when stored projects increased much. To avoid this situation, users can search any value in the project. For example; users can list projects which project name include “ROCK” or AHU airflow is greater than or equal to 50.000 m3/h or “Klingenburg” branded rotary heat recovery module including AHUs.
The design of AHU can be seen from the sides, top, front and rear. During the selection, the drawing of AHU on the screen is vectorial and all of the AHU selection can be exported by DXF format in AutoCAD. The drawing on screen while designing and the drawing in AutoCAD will be same.
The technical reports can be transferred into PDF, Excel, Word or Html formats. You can also send the file in that format via e-mail from the program.
With the help of 90° and 180° rotation modules, AHUs can be designed with two or more layers without using heat recovery module. It is also possible to design an AHU in the shape of maze by 90° rotation module.
Users can identify new module-based accessory types, select them in preferred AHUs and add automatically to the cost of AHU.
Users can specify a new AHU dimension specific for that AHU except the standard AHU modules during selection. It is also possible to specify module-based special dimension within the AHU.
Users can obtain detailed production information of all material and workmanship used during the production of AHU, based on module, AHU and project. You can calculate production duration of AHU.
Interior Lighting (Lightening with Switch): In-module lightening
Observation Window: Double-glass window for observation purpose
Door Sensor: Safety switch for doors
Roof (Sheet Metal/Canvas): Waterproof solutions for external units
Factory Prewired Unit: Prewiring option decreases the amount of electrical work at site in a way that all in-unit cablings are excluded from scope of electrical contractor. Jack type connections and hidden cablings prevent any complications during assembly or future use.
