Source: https://evercoils.com/resources/dry-cooler-vs-condenser/ TECHNICAL NOTE # Dry cooler or air-cooled condenser? Similar construction can serve different thermodynamic duties. ## Dry cooler A dry cooler transfers heat from a circulating liquid to ambient air. Water or a water-glycol solution is a common application; the intended operating mode does not rely on condensing that circulating liquid. ## Air-cooled condenser A condenser rejects heat from refrigerant, including its change from vapor to liquid. Refrigerant, design pressure, circuiting and operating conditions shape its construction. ## Why the distinction matters V-shaped coils and top-mounted fans can appear in both. Identify the fluid and duty from the specification or nameplate, not fin color or external appearance. ## What to send with an enquiry Include fluid or refrigerant, design pressure, inlet and outlet conditions, duty and intended equipment arrangement.

Source: https://evercoils.com/resources/rating-conditions/ TECHNICAL NOTE # Why a kW rating needs operating conditions. Thermal capacity is meaningful only when its operating basis is defined. ## Ambient temperature The available temperature difference between the coolant and air affects heat transfer. A rating at one ambient temperature cannot simply be reused at another. ## Fluid and concentration Fluid properties influence heat transfer and pressure drop. State the coolant composition and concentration. ## Flow and fan conditions Fluid and air flow affect performance, pressure losses and energy use. Define the conditions associated with the stated duty. ## Compare like for like Compare quotations at the same thermal duty, temperatures, fluid conditions, pressure-drop limits and fan operating basis.
