United Heat Transfer (UHTL) is a nano cap SME company incorporated in 1995 engaged in manufacturing of wide spectrum of heat exchangers like Shell and Tube heat exchangers (Hx), air cooled heat exchangers, process flow skids, pressure vessels etc.
Why the DC cooling value chain / Vertiv association is worth considering ?
As rack densities go up with each successive GPU class , DC cooling assumes utmost significance with liquid cooling and immersion cooling becoming an absolute necessity.
United Heat Transfer Ltd (UHTL) is present inside the CDU which is the interface b/w the secondary loop and the primary loop (Was explained in detail in Aeroflex thread by @phreakv6) .
UHTL seems to have capabilities is the Heat exchanger , Piping systems and Skid/ Frame integration inside the CDU. Below is the different components of a CDU.
“Onboarded Vertiv as a new customer and has successfully developed a Cooling Distribution Unit (CDU) Solution “ - In the concall the management clarified that this is a trial order that they have received from Vertiv and these are for some specialized piping which forms the part of the CDU . This was slated to be supplied by some other company and since they couldn’t do it the order came to UHTL.
Current trial order from Vertiv is only worth Rs 10-20 Lakhs . The validation is complete. The commercial order might be Rs 10-20 Cr value as per management.
In heat exchangers , there are 3 main categories , 1. Plate Hx, Shell and tube Hx and Air cooled Hx. UHTL is into Shell and tube and Air Cooled HX.
UHTL has been receiving continuous orders from the likes of Siemens Energy, GE , IngerSol Rand, Kirloskar Pneumatic etc albeit for small values.
Unexecuted order book as on 29th May 2026 stood at c. 34 Cr.
New manufacturing building of 50k sq ft commenced in Talegaon and expected to be operational by Q3 FY 27.
In H2 Fy 26 UHTL added 57 new customers out of which 16 were international.
At the current P/E of C. 35 , based on the FY 28 (E) , EPS the stock can trade at c. 295 Rs which is 3x from the current levels.
Risks
Nano cap stock trading in SME exchange with minimum lot size. Liquidity is low . Seems to be trading at circuits on the upper and lower side .
The Vertiv order is trail in nature . Unlike Aeroflex, there are several un certainities. Entire thesis might back fire.
Stock is already up 70% since H2 results. (ATH is Rs 110 , above current levels).
Disclosure : Invested in personal account at around Rs 80. Can add or exit without prior intimation. DYDD.

Thanks for a new thread on a new SME company. Company is into a specialised field though small in size. It can turn into a good prospect. But what matters most is the management quality and competition. Please throw some light on technical capabilities and peer companies. Is KRN a competitor?
United Heat Transfer (UHTL) mentioned Patels Air temp and Loyal equipments as their competitors in the listed space in the investor call. KRN heat exchangers in my limited understanding is not a competitor to UHTL.
KRN v/s UHTL in Data Center cooling domain
UHTL is supplying the heat exchanger core inside a CDU — a liquid-to-liquid device that interfaces the IT secondary cooling loop with the facility chilled water primary loop. This is a high-spec, engineered-to-order component sitting at the thermal heart of a liquid cooling system. UHTL manufactures Shell and Tube Hx.
KRN is supplying fin-tube coils for rear-door heat exchangers and CRAC/CRAH units — the air-side layer of cooling. These are used in hybrid cooling architectures or as supplemental cooling alongside liquid cooling. At ~15% of KRN’s revenue already, this is a more mature DC revenue stream than UHTL’s first CDU delivery scheduled for June 2026.
In terms of future potential within the DC cooling stack, UHTL has a higher-value application
The CDU liquid-to-liquid heat exchanger is more thermally critical and commands higher margins than an air-side coil — but KRN already has proven, recurring DC revenue while UHTL is still at first commercial delivery stage. Risk profile is inverted: KRN has execution proof, UHTL has higher upside if it executes.
Management Quality
I don’t have much info regarding the management quality other than the fact that the top management is comprised of brothers Yogesh Patil and Vivek Patil and their kin. I couldn’t find any reported red flags on the top management from rudimentary search. UHTL is a low volume made to order B2B business with expertise in handling welding , complex metallurgy , handling materials as diverse as SS, Hastelloy, Inconel etc. They seem to have marquee clients placing orders (The likes of Atlas Copco, Siemens Energy, GE, Ingersolrand, Cummins and now Vertiv).
Be very careful while comparing uht with aeroflex. They only received a trial order. They have no contract for future orders and it all depends on validation with this trial order. Even uht management deny aeroflex as their peer. uht has capabilities on paper but not same as aeroflex.
Aeroflex on the other hand has exclusive contract with vertiv. Beyond contract both have manufacturing plants side by side in pune. Hence, it is flying so high.
Around 2014-15, I have met Vivek Patil few times and visited their plant in Nashik for exploring sourcing opportunities (UHT as a supplier) while I was working. At that time, we have given them trial order. But we did not pursue it further due to multiple reasons. As you can see, it was almost 12 years back so they may have improved/changed a lot.
