This page shows an example of the ON-LINE calculations of products from the production program of Mandík, a.s., with their full permission to illustrate the calculation together with the product description.

The use of the calculation is very simple:

  1. In the „Values“ section set the desired parameters.
  2. In the table “Selecting the damper size” you will then see the resulting values for all damper sizes.
  3. The contents of this table can be changed by selecting a new quantity in the row of menu buttons below the heading.
  4. The contents of the “Calculated Values” section are updated according to the selected size in the “Flap dimension selection” table.

The MANSEL program for calculating HVAC components

The on-line calculation above on this page contains a sample of fire damper calculations and serves as a presentation sample of our work. We recommend downloading and installing the full version of MANSEL for calculating other HVAC components. MANSEL is designed as a free download for all potential buyers. We created this program upon request by Mandík, a.s., with which we have authorized use of these works as reference material. The program is used for the selection and calculation of air-conditioning components from the production program of Mandík, a.s.

By installing a desktop version of this program, you will receive a version with enhanced functionality, which is not available on our site. For example, these features include:

  • Work with project designs
  • Saving and retrieving selected parts from/to a file
  • Printing

Regulation damper RKTM description

The copyright for the description of the product belongs to Mandík, a.s.

The dampers consist of a frame, blades fitted with air seal at the perimeter, and a control actuator. They are used to shut off the duct or to control the air flow by choking the flow. Tightness in accordance with EN 1751 across the body: class C and across the blade: for dampers to 0,3 m² class 2, for dampers over 0,3 m² and min. 6 blades class 3. The dampers are destined for maximal velocity of air flow 12 m.s. The dampers are intended for environment protected against weather impacts with the classifi-cation of climatic conditions class 3K5, without condensation, frost, ice formation, and without water even from other sources than rain according to EN 60 72133, change A2, with temperature range from -20°C to +80°C. If the electrical elements are mounted on the damper, temperature range is narrowed by the electrical elements.

Characteristics

  • For regulation and airflow cut off inside the duct
