Description
BD-18 Non-Code Blow-Off Separator Tank
The Rema BD-18 non-code blow-off separator tank is designed for boiler blowdown applications from 30 to 50 HP where a non-ASME tank is permitted. This larger separator helps cool and separate high-temperature boiler discharge before it reaches the drain in higher-capacity boiler installations.
Built from heavy-gauge steel, the BD-18 provides increased capacity and a larger blow-off inlet for larger boiler systems while maintaining a compact, maintenance-free separator design.
Why Choose the BD-18
- Designed for boilers from 30 to 50 HP
- 18" diameter for larger-capacity applications
- 21 gallon capacity
- 1-1/2" blow-off inlet
- Heavy-gauge steel construction
- Simple, maintenance-free separator design
- Commonly used alongside condensate return systems in boiler room projects

Typical Application
The BD-18 is intended for larger boiler blowdown installations where added separator capacity is needed. It helps receive hot blowdown discharge, vent flash steam, and direct cooled water toward the drain connection in applications where a non-code blow-off separator is acceptable.
Important Before Ordering
This is a non-ASME, non-code blow-off separator tank.
The buyer, contractor, engineer, or end user must verify that a non-code tank is acceptable for the installation and permitted by local code, state boiler regulations, the authority having jurisdiction, and the owner’s insurance requirements.

Frequently Asked Questions
What boiler size is the BD-18 designed for?
The BD-18 is designed for boiler blowdown applications from 30 to 50 HP.
Is the BD-18 an ASME code tank?
No. The BD-18 is a non-ASME, non-code blow-off separator tank. The buyer must confirm that a non-code tank is acceptable for the installation.
What is the BD-18 tank capacity?
The BD-18 has a capacity of approximately 21 gallons.
What is the blow-off inlet size?
The BD-18 includes a 1-1/2" blow-off inlet.
Are blow-off separator tanks commonly used with condensate return systems?
Yes. Blow-off separator tanks and condensate return systems are commonly purchased for the same boiler room projects when blowdown handling and condensate recovery equipment are being updated together.
What is the maximum boiler pressure rating?
The BD-18 is listed for applications up to 200 PSI maximum boiler pressure.
