Tank System Controls

SeaLand® DTD series tank discharge controls

Allows manual or automatic discharge pump operation

DTD Tank Discharge Controls

Where overboard discharge of a waste holding tank is permitted, SeaLand DTD controls offer many options to match preferred methods of tank discharge operation. A key-operated switch allows the user to activate the discharge pump, or set the DTD panel for semi- or fully-automatic operation, depending on the DTD model.

All panels include a green light that indicates when the discharge pump is running. DTD controls can be used with a discharge pump operating on the same voltage and a maximum circuit rating of 20 amps.

Key Benefits – DTD01, DTD02:

• Manually activates pump to discharge holding tank contents directly overboard in unrestricted waters
• Green light indicates when discharge pump is running; reminds operator to shut off pump to prevent burn-out
• Keyed switch provides U.S. Coast Guard-approved security when key is removed; no padlocks or other mechanical fasteners are required
• When integrated with DTM04 tank monitor system, discharge pump automatically shuts off when tank is empty
• DTD02 panel provides warning indicator and prevents discharge pump operation if seacock is closed; prevents pump or boat damage

Fully automatic SeaLand® DTD systems

Complete holding tank management for offshore boats

Combined with SeaLand discharge pump and DTM04 four-level tank monitor system (sold separately), DTD01A or DTD02A tank discharge controls offer fully automated monitoring and discharge of holding tank contents. When re-entering restricted “no discharge” waters, the switch can be turned off and the key removed for U.S. Coast Guard-approved security.

Key Benefits – DTD01A, DTD02A:

• Automatically discharges holding tank contents directly overboard in unrestricted waters
• Automatically shuts off pump when discharge is complete
• DTD02A panel provides warning indicator and prevents discharge pump operation if seacock is closed; prevents pump or boat damage
