01. Intro

Project Description

ECOS M24 Outer unit

Zero-emission technology for conditioned transport

ECOS M24 is a new transport refrigeration solution specifically designed for electric vehicles, allowing the delivery of temperature-sensitive foodstuff or pharmaceutical products to their destination reliably and without emitting any CO2.

Outer & Inner unit

Refrigeration system

Ecos M24 system consists of an outer and inner unit. The outer unit is part of a refrigeration system that mounts on the roof of the cargo van. The inner unit cools the inside of the cargo.

Up to 15 % more payload at same cooling capacity


Natural refrigerant (GWP<1)


Maximum driving range thanks to best volumetric efficiency


Ideal for electric light commercial vehicles < 3.5 tons


Cost and energy efficient


Concept Stage

A new fresh visual needed to be created to reflect modern emission free refrigeration technology designed specifically for electric vehicles.

ECOS M24 product line needed to stand out on the market of mobile refrigeration units and at the same time reflect new trends in automotive design relating to electric mobility.

Werkemotion design team create unique design language for both refrigeration units thanks to complete design process from hand sketch - 3D concept model - Manufacturing data.

Prototyping Stage

Both units had specific technical demands shaping final design. Intake and outtake grills of both units had to be designed to meet individual airflow requirements to ensure proper function of the system.

During design process the goal was to keep similar design language traits on both units despite the differences in construction of the two units.

WE prepare all outer surface with all manufacturing requirements.

03. Concept Phase

Sketch Development

During the sketch phase, we are looking for a new design language and exploring how used materials and manufacturing processes impact the design.

04. Development

Design Process

Werkemotion Design Studio closely collaborated with PBX engineers to merge a new visual identity with all technical requirements. The result is a product that stands out at the same time in design and technological innovation. Both aspects are necessary to differentiate the brand from the competition and attract new customers.
