We specializes in designing a variety of HVAC systems for private, commercial and industrial sectors. We are always aspiring to make simple and efficient designs, our field experience enables us to make designs that are taking into account the constructor perspective which helps to reduce construction faults and improve the quality of the assembled system.The company portfolio includes the planning and designing of various HVAC systems:

  • Water cooled
  • Direct expansion
  • VRF (variable refrigerant flow)
  • Water heating heat pump
  • VAV (Variable air volume)
  • Underfloor heating
  • Filtration
  • Smoke exhaust
  • Fume hood exhaust
Our Process
Inquiring the client regarding the system requirements and constraints.collecting relevant documents such as: architectural drawings, construction drawings etc.
Examine the collected data and perform the relevant calculations, such as: thermal heat gains/losses, available technical areas, etc.
Choosing system type that fits the constraints and spaces climate requirements Defining: end units, central units, pipelines, air ducts, pumps and fans Creating CAD drawings Creating equipment table, BOM(bill of materials), technical specification.
Sketch initial concept design that describes the system as a whole that includes power consumption estimation.
Sending the design to the client for final review making final adjustments according to client remarks.
Our Clients


Laboratories HVAC System
Area: 8,00 SQM Temperature: 23 ± 1°C


HVAC temperature control was needed for Three types of Laboratories : electrical, chemical and biological. Each laboratory included special hoods. The Hoods were equipped with variable air volume valves and were controlled with a door height sensor. Due to the changes in air quantity suctions from each room there was a need to supply treated fresh air to the central corridor.

Sarael Chen-Tov

David provided planning and supervision services for several projects, From my acquaintance with David, I can say that he is professional, responsible, thorough and diligent in every task he takes on.

Nitzan Haviv
Manager of Operations

As a foodtech company at the beginning of its journey, it was necessary to build a work method from the ground up, learn, research and find Practical solutions to the challenges we faced, David learned our process, "got in the thick of it" and provided a detailed design that met the complex requirements of the manufacturing process program.

Mor Malka
Construction Manager

David from Kelvin entered into the planning of the systems at the end of the architectural design and during construction of the factory. David provided us with detailed plans and effective solutions on the fly. David contributed a lot to the successful completion of the project.

Nir Shani
Factory Engineer

We used the services of David Agam, in the planning of several projects at the Dockert factory. I would like to state our satisfaction with sharingWorking with David, who acted professionally and provided effective solutions while meeting the project schedule, thereby helping usreach our results and requirements.

Rami Moshe
Director of Operations and Logistics

David Agam from "Kelvin" was our air conditioning consultant in two projects to establish new laboratories with a total area of about 800 square meters. The experience that David brings with him from the field, along with the knowledge of planning, certainly helped in achieving the goals and great success in both projects.
