Keep people and equipment productive
Heat does not need to shut down the whole facility to cost money. It can slow work, shorten maintenance windows, push equipment toward derating, and create quality risk in one critical area.
Industrial cooling
THEEVU ENERGY Put cold air where heat is costing you throughput.
Refrigerant-free air-cycle cooling for hot work areas, wasted compressed air, limited electrical capacity, water-constrained sites, and places where another cooling project is too slow, too expensive, or too hard to service.
Cool the exact bottleneck
Keep work moving
Add no refrigerant at point of use
Use pressure more intelligently
Prove ROI in a focused pilot
Benefit
Turn hot spots into manageable zones. Send cold air to the operator station, cabinet, process area, or equipment bay that is driving discomfort, slowdowns, derating, or avoidable downtime.Benefit
Use air instead of another refrigerant loop. Add targeted cooling without putting another refrigerant system inside the problem area. That helps sites dealing with leak management, water limits, space limits, or service constraints.Benefit
Recover value from pressure you already paid for. Where compressed air is already being reduced or vented, Theevu turns that pressure drop into a chance to create cold air and recover useful energy.Why it matters
The expensive cooling problem is often smaller than the building.
Turn wasted pressure into useful cooling
When a plant lowers or vents compressed air pressure, it is often losing energy it already paid for. Theevu looks for places where that pressure drop can help make cold air.
Avoid the big-project trap
Instead of waiting on a major chiller, ductwork, water, or electrical upgrade, a focused pilot can test whether targeted cold air solves the specific bottleneck directly.
Where it fits
The best first customers already know where heat or pressure is costing them.
- 01Compressed-air and pressure-drop owners
Create cold air and recover energy from pressure that is already being reduced, regulated, or vented.
- 02Plant, EHS, and operations teams with hot work cells
Improve comfort, reduce heat-driven delays, and protect production areas that fans or standard spot coolers cannot handle well.
- 03Facilities teams with refrigerant, water, or power limits
Add targeted cooling capacity without starting with another refrigerant loop, water-heavy system, or major electrical upgrade.
- 04Edge and legacy critical facilities
Attack hot spots, stranded capacity, or aging cooling rooms with a separate cold-air path.
- 05High-density compute environments
Build a future path for auxiliary cooling where power, water, service access, and heat density are all under pressure.
System
The system uses air as the cooling medium, then sends cold air to the problem area.
An electric motor pushes air through the system. Heat and moisture are removed. The air expands, gets colder, and goes to the target area. If the expander produces usable power, that recovered power is counted separately from the power required to run the system.
Step 1
Incoming Air
Outside air or return air enters through a filtered inlet. The starting air conditions matter because they set the baseline for the whole test.
- Pressure
- Starting air pressure: TBD
- Temperature
- Starting air temperature: TBD
- Energy flow
- System boundary starts here
- Measurement needed
- Air pressure, temperature, humidity, and dewpoint.
Any recovered power is shown separately from the power used to run the system, so buyers can see the real net result.
Pilot proof
A good pilot should make the buying decision obvious.
The proof is practical: did the target area get colder, did the operation run with less disruption, and did the net energy picture beat the current workaround?
1
What changed on the floor?
Lower local temperature, safer work access, steadier equipment, less derating, fewer heat-driven slowdowns, or more usable operating hours.
2
What did the energy bill see?
Total power in is counted. Recovered power is credited separately. The buyer sees the real net result instead of a confusing gross-output story.
3
What is the rollout case?
The pilot should show where the system pays off, where it does not, and which similar work areas, air branches, or rooms are worth targeting next.
Cooler work area
More usable capacity
Less heat-driven downtime
No added refrigerant loop
Recovered energy credited
Clear payback story
Pilot value
What a pilot should give the buyer.
A before-and-after comparison
Current cooling equipment, current energy use, site temperatures, pressure and flow data, duty cycle, and the cost of leaving the bottleneck alone.
A clear operating range
Where the system runs well, where it needs redesign, how much cold air reaches the target, and whether moisture, icing, noise, vibration, or service access create limits.
A rollout decision
A clear yes, no, or redesign recommendation based on safety, net cooling efficiency, avoided cost, installation complexity, and repeatability across similar sites.
IP and diligence
The patent story helps. The buyer value has to stand on its own.
Why it matters
The filings support a different path to industrial cooling: use air, remove heat, expand the air to make it cold, and recover useful energy where the physics and site conditions allow it.
What buyers should care about
Can the system cool the real bottleneck, lower the operating pain, fit safely into the site, and create a payback case that beats the current workaround?
What diligence should confirm
Ownership, claim scope, freedom to operate, service requirements, measured performance, and the path from one successful pilot to repeatable deployments.
Pilot design
A strong pilot starts with one painful bottleneck.
1. Name the cost
Identify the work area, pressure drop, equipment cabinet, process area, or cooling limit that is costing money, time, safety margin, or production flexibility.
2. Keep it controlled
Choose a safe branch or non-critical area where the test can be bypassed, supervised, and measured without putting production uptime at risk.
3. Define the win
Agree upfront on the temperature change, runtime, total power use, recovered power, safety requirements, and payback logic that would justify rollout.
