What Sollie does

Sollie (legally Ing. Björn Sollie AB) is a privately held, single-location engineering consulting firm headquartered in Lund, Sweden. Founded in 1984 by Björn Sollie, the firm operates with a staff of 1–10 and provides independent advisory and design services for industrial refrigeration and heat pump installations, with a focused specialization in ammonia (R717) refrigerant systems. The practice serves enterprise clients across the food industry, process industry, energy centers, district cooling, recreation facilities, and industrial heat recovery, with reference customers including Tetra Pak, Alfa Laval, Ramböll, Sweco, Norconsult, Lithells, Pinos, and Stavanger.

The firm's core offering is site-built (platsbyggda) cooling and heat pump systems — custom-engineered installations designed in-house rather than factory-assembled units — which the company argues deliver superior long-term economics, component flexibility, and upgradeability. Sollie executes projects across the full engineering lifecycle, including concept studies, pre-project planning, detailed design, construction work management, and tender documentation. A differentiated service is independent, vendor-neutral evaluation of capacity-increase alternatives and refrigerant-charge reduction on large ammonia installations.

Commercially, Sollie operates as a project-based professional services firm with a sales-led, direct-engagement go-to-market model. Revenue derives from engineering service engagements rather than software, products, or recurring licenses. The firm is founder-owned, has no disclosed external investment, no subsidiaries, no M&A activity, and operates exclusively within Sweden and adjacent European markets. No digital product, app, API, or AI/ML capability is present in the offering.

Functional benefit

Products and services

• Site-Built Cooling and Heat Pump Installations (Platsbyggda kyl- och värmepumpsanläggningar) Custom-built cooling and heat pump installations engineered on-site for industrial clients, offering long-term economic advantages over factory-built units, flexible component combinations, and easier replacement of main components when better technology becomes available.
• Process Cooling (Processkyla) Technical consulting and engineering for industrial process cooling, where precise temperature control is critical to product quality, production throughput, and energy efficiency.
• Industrial Refrigeration Consulting (Industriell kylteknik) Independent technical consulting on industrial refrigeration based on extensive experience with industrial refrigeration technology and ammonia (R717) systems, covering concept studies, pre-project engineering, detailed design, construction work management, and tender documentation.
• Food Industry Refrigeration (Livsmedelskyla) Refrigeration engineering services for the food industry, addressing temperature control requirements across food production, processing, storage, and distribution where temperature is a critical process parameter.
• Industrial Heat Pump Technology (Industriell värmepumpsteknik) Engineering and consulting on industrial heat pumps used to capture and reuse energy that would otherwise be lost in various industrial processes, supporting energy efficiency and energy recovery objectives.

Broad incumbents

• Johnson Controls: Global HVAC, refrigeration, and building controls incumbent with significant industrial refrigeration and heat pump capabilities. Comparable to Sollie in the industrial cooling end-market, though operating at vastly larger scale across a much broader portfolio.
• COWI: Major Danish engineering consultancy with industrial and energy expertise. Comparable as a Nordic engineering services firm serving similar industrial clients, though offering a much broader multidisciplinary portfolio.
• AFRY (formerly ÅF): Major Swedish-Nordic engineering consultancy with industrial process and energy divisions. Comparable to Sollie as a Nordic engineering services firm serving food and process clients, though operating at much larger scale across many disciplines.
• Trane Technologies: Global HVAC and refrigeration equipment manufacturer with strong industrial and commercial cooling presence. Overlaps with Sollie's industrial cooling design domain but competes as an equipment vendor rather than an independent advisor.
• Alfa Laval: Global heat transfer and separation equipment manufacturer with strong industrial refrigeration portfolio. Comparable to Sollie in the industrial cooling end-market, though operating as an equipment manufacturer/vendor rather than an independent advisor.
• Sweco: Leading European engineering consultancy with industrial and energy practices across the Nordics. Comparable to Sollie as an engineering services provider serving similar industrial client segments, but operating across many disciplines at much larger scale.
• Ramböll: Major Nordic engineering consultancy with energy and process industry practices. Comparable as an engineering consultancy serving similar industrial clients in the Nordics, though operating at vastly greater scale across many service lines.

Others

• Danfoss: Global refrigeration and HVAC components manufacturer headquartered in Denmark. Connected to Sollie as a major component supplier into the same industrial ammonia and heat pump projects Sollie designs; ecosystem participant rather than direct competitor.

Direct peers

• Star Refrigeration: UK-based independent industrial refrigeration specialist providing ammonia (R717) system design, installation, and consulting. Directly comparable to Sollie as a focused industrial cooling engineering firm with deep ammonia expertise serving food and process industries.
• ICS Cool Energy: European industrial cooling and process temperature control specialist offering temporary and permanent refrigeration solutions. Comparable to Sollie in targeting industrial process cooling customers across food and process industries.
