Gracemar Farms — Dairy Chiller Retrofit Project
Transforming Dairy Challenges Into Energy Solutions
Alpine Refrigeration partnered with Gracemar Farms in Chilliwack, BC, to deliver a custom dairy chiller retrofit that solved chronic ammonia issues and extended equipment life.
The retrofit integrated an advanced clean-room design and heat recovery, reclaiming waste heat to provide warm water for livestock and boiler preheat.
These upgrades created a more sustainable, cost-efficient system built to last for decades.

Gracemar Farms Dairy Retrofit
The Challenge
Gracemar Farms was operating with outdated refrigeration equipment that created chronic ammonia issues and limited system reliability. Equipment lifespans averaged only 7 years, leading to frequent replacements, high costs, and constant maintenance demands.
The existing system also wasted significant amounts of heat energy, offering no recovery process to repurpose excess thermal output. This inefficiency raised operating expenses and missed opportunities to support livestock operations more sustainably.
At the same time, regulatory pressures around air quality and environmental compliance meant a long-term solution was needed — one that would improve safety, extend system life, and support sustainable farming practices.
Why Change Was Needed
- Chronic ammonia issues creating air quality and safety risks
- Short equipment lifespan (7 years on average, costly to replace)
- No heat recovery, wasting valuable energy
- Pressure to improve sustainability and qualify for agricultural grants
Engineered for Performance
Alpine's Hybrid Heat Pump Retrofit Solution
Alpine engineered a custom dairy chiller retrofit that addressed Gracemar Farms' ammonia challenges while extending equipment lifespan. Instead of replacing the system with another short-lived setup, Alpine designed a solution built for long-term durability and efficiency.
By integrating an advanced clean-room layout and heat recovery system, Alpine captured waste heat that had previously been lost, repurposing it to provide warm water for livestock and boiler preheat. The result: improved air quality, reduced operating costs, and a system designed to last decades instead of years.
How We Did It
- Custom Chiller Design: Engineered for clean-room performance to improve air quality and reliability
- Heat Recovery Integration: Captured waste heat and repurposed it for drinking water and boiler preheat
- Durability Upgrades: Retrofit projected to extend system lifespan to 25–30 years (vs. 7 years before)
- Sustainability Gains: Enabled eligibility for IAF grants supporting sustainable farm practices

Verified Results
Proven Performance
Early results from the Gracemar Farms dairy chiller retrofit show a dramatic improvement in system longevity and efficiency. Equipment that once lasted only ~7 years is now projected to run for 25–30 years, cutting capital replacement costs and ongoing maintenance demands.
The retrofit's integrated heat recovery system also captures energy that was previously wasted, repurposing it to provide warm water for livestock and boiler preheat. This innovation has reduced operating expenses while supporting more sustainable farm operations.
The project further enabled Gracemar Farms to qualify for IAF sustainability grants, underscoring Alpine's role in delivering not just technical solutions but financial and environmental benefits as well.
- 25–30 year projected system lifespan (vs. ~7 years before)
- Reclaimed heat repurposed for water and boiler preheat
- Qualified for IAF sustainability grants
This retrofit gave Gracemar Farms a cost-efficient, long-term solution that improved reliability, lowered operating costs, and advanced sustainability. The design is serviceable, durable, and sets a new benchmark for agricultural HVAC retrofits across British Columbia.
Beyond Gracemar Farms
Scalable Agricultural Retrofits Across BC
The Gracemar Farms dairy chiller retrofit proved that agricultural HVAC upgrades can be practical, repeatable, and scalable. By working with existing infrastructure and integrating heat recovery, Alpine created a retrofit model that avoids costly replacements while delivering long-term efficiency.
This retrofit model has already gained attention from other dairy and agricultural operations across BC. Rising energy costs and sustainability requirements mean farms need solutions that balance budget, compliance, and efficiency — and Alpine's approach delivers exactly that.
Why It Matters for BC Agriculture
- Scalable model: repeatable across farms and processing facilities
- Livestock-focused: supports air quality and warm water for animal health
- Sustainability ready: helps farms qualify for IAF and Net Zero programs
- Built to last: durable design projected for 25–30 years of service
