What we do for mission-critical environments
Six scopes, one delivery org
Engineering, controls and installation from one accountable team, plus 24/7 service in Quebec and Ontario — the scopes operations directors usually buy from three or four vendors, run by one.
High‑density cooling — CRAC, in‑row, rear‑door, liquid
Precision air conditioning and liquid‑cooling strategies for high‑density compute and high‑thermal‑load environments — engineered for the rack densities you actually run, not catalog defaults.
Redundant chilled-water and controls
N+1 and 2N redundant designs for chilled water, distribution, and controls — engineered so a single component failure never takes the load offline.
Cleanroom and laboratory environments
Pressurization, humidity, and particle control for cleanrooms and laboratories — the tight thermal and pressure tolerances research and biotech facilities require.
WebCTRL® monitoring and proactive alerts
Real-time WebCTRL® / Automated Logic monitoring, automated alerting, and continuous performance optimization — built on the platform Kolostat is an authorized partner for.
Fast-track retrofits
Integrated design-build compresses the engineering-to-commissioning timeline so retrofits land on the operations calendar your business can actually accept.
24/7 preventive maintenance contracts
Preventive maintenance plans for facility directors who cannot afford surprises — quarterly or biannual inspections, BMS monitoring, priority dispatch, written reports — in Quebec and Ontario.
The team behind the controls
The engineering depth a mission-critical environment requires
A mission-critical cooling plant is a controls problem as much as a mechanical one. Kolostat's engineering, controls, and energy teams operate inside the same delivery org — so the people who design the redundancy, commission the BMS, and — for clients in Quebec and Ontario — respond to a 3 a.m. alert are working from the same documentation.
- Real-time monitoring on Automated Logic / WebCTRL® — Kolostat is an authorized partner
- Precise control, automated alerts, and continuous performance optimization
- Digital-twin integration where the operations cadence justifies it
- Multidisciplinary team — engineers, control technicians, project managers, service pros
Why operators choose Kolostat for mission-critical
The four levers our clients actually invest in
Operations directors, facilities VPs, and colocation ops teams shortlist on these four. Each is a sourced claim — no marketing varnish.
Speed without engineering shortcuts
Integrated design-build collapses engineering, fabrication, install, and commissioning into one accountable timeline — so retrofits land inside the operations window your business can absorb.
Redundancy, validated by transparent audits
N+1 / 2N redundant cooling and controls designed to protect operations 24/7 — with transparent audits behind the redundancy claim, not marketing language.
Around 30% energy savings on critical cooling
Annual energy savings of roughly 30% on critical cooling systems on past mandates — validated by transparent audits and delivered without compromising uptime.
Specialized on-call coverage, 24/7
A dedicated dispatch line, proactive support, and complete service management in Quebec and Ontario — for clients whose downtime cost is measured in minutes, not hours.
No-downtime methodology
How we keep your environment online during a retrofit
Working in a live mission-critical environment is a sequencing problem. The methodology below is how we plan the work so the live side is never the side being touched.
Discovery against your runbook
Site walk with a senior engineer against your existing runbook — measured against the cooling architecture, maintenance windows, and uptime SLAs you actually operate to.
Redundant-side-first sequencing
Work staged so the redundant side absorbs load first. Cutovers scheduled in coordination with your operations team — so the live side is never the side being touched.
Live-environment execution
The same discipline our crews apply to occupied office and multi-residential buildings — temporary services, off-hours invasive work, communication discipline — applied to live mission-critical environments.
Commissioning with monitored handover
Load testing, controls commissioning, and a monitored handover on Automated Logic / WebCTRL® — with proactive alerts wired into your ops cadence before the project closes.

Operations-director FAQ
What our clients ask before signing on
How do you handle a no-downtime cooling retrofit on a live data center?
We sequence the work so the redundant side absorbs load first, schedule cutovers in coordination with your operations team, and apply the same live-environment discipline our crews use in occupied office and multi-residential buildings — temporary services, off-hours invasive work, communication discipline. The work plan is built around your maintenance window, not ours.
What level of redundancy do you design to?
We design redundant chilled-water and controls topologies that match the availability SLA the operations team has actually committed to — typically N+1 or 2N for chilled water, distribution, and controls. The redundancy claim is validated by transparent audits, not marketing language.
Do you handle laboratory and cleanroom mechanical scope?
Yes. Pressurization, humidity, and particle control for cleanrooms and laboratories is a core mission-critical scope — the same precision-air-conditioning and ultra-precise air-quality engineering we deliver for data centers, applied to research, biotech, and high-tech production environments.
How much energy can we realistically save on critical cooling?
On past mandates we have delivered annual energy savings of roughly 30% on critical cooling systems, without compromising uptime. The number is validated by transparent audits — we instrument the plant during commissioning and measure savings against baseline, so the figure your operations team reports is sourced from the site, not from an estimate.
Where do you deliver mission-critical projects?
Across Canada. Data center, laboratory and cleanroom projects are delivered from our Laval head office and our offices in Montréal, Toronto, Newmarket and Calgary. Preventive maintenance, 24/7 dispatch and specialized on-call coverage are provided in Quebec and Ontario.
Do you have 24/7 dispatch for cooling failures on a data center?
Yes, in Quebec and Ontario. One dispatch number — 514-333-7333, option 1 — backed by a fleet of 25+ service trucks across Greater Montréal and the GTA, plus specialized on-call coverage for mission-critical clients. Data centers are a core sector for our preventive-maintenance contracts and 24/7 emergency dispatch.
What monitoring and controls platform do you commission on?
Real-time monitoring on Automated Logic / WebCTRL® — Kolostat is an authorized ALC / WebCTRL® partner. We commission dashboards, proactive alerts, and continuous performance optimization, with digital-twin integration where the operations cadence justifies it. The platform is technology-neutral on the equipment side and integrates with non-ALC plant.
