Hexonic LC110-40-2 brazed plate heat exchanger, 2", 40 plates, PN 25
- Application: large substations, industrial processes, chillers
- Heat capacity: ~160-400 kW (depending on flow rate and ΔT)
- Nominal pressure: PN 25 (25 bar)
- Connection: G 2" external threads
Where LC110-40-2 is used
Hexonic LC110 — C size (larger than B) plate exchanger, plates ~466 × 258 mm. The 40-plate pack is used in large-capacity central heating substations, industrial heat recovery processes, chiller primary loop separation, commercial buildings, and large-scale district heating consumer stations. G 2" connections support high flow rates (up to ~20-25 m³/h).

Heat transfer capacity — quick calculation
General formula: P = Q × ΔT × 1.163 (kW, Q m³/h, ΔT °C). LC110 plates are sized for higher flows — G 2" connections handle up to ~25 m³/h of water with acceptable Δp.
Example for heating mode (primary 90/70 °C → secondary 65/40 °C): at Q ≈ 12.0 m³/h and effective ΔT ≈ 20 °C → P ≈ 280 kW. At 25 °C ΔT, capacity scales proportionally.
When to choose LC110-40-2
- Large-capacity substations (~160-400 kW)
- Industrial process heat recovery
- Chiller cooling system buffer separation
- When flows require G 2" connections and pressure stays under 25 bar
When to choose an alternative
- Pressure above 25 bar → gasketed exchanger with stronger frame
- Flows >30 m³/h → LC170 or gasketed M6/M10 class
- More compact solution at same capacity → LM110 (micro-channel)

Frequently asked questions
How does LC110 differ from LB60?
LC110 has larger plate area (~466 × 258 mm), designed for higher flows and higher capacity. LB60 — mid-capacity, more compact, G 5/4" connections. Choose LC110 when capacity is >250 kW or flow >10 m³/h.
Can glycol mixtures be used?
Yes, up to 50 % ethylene or propylene glycol with appropriate inhibitors.
What maintenance is required?
Brazed construction — no disassembly needed. CIP flushing every 3-5 years if fouling signs appear.
Is it suitable for potable water?
Yes. AISI 316L plates and copper brazing meet WRAS/DVGW requirements.
Is insulation needed?
APFI series insulation shell is recommended — fits LC110 plate count groups (10-20, 21-40, 41-60, 61-80, 81-100).
